In the title solvated salt, [Ag(C18H15P)4](CF3CO2)·C2H5OH, the AgI atom is coordinated by four P atoms from triphenyl­phosphane ligands in a distorted tetra­hedral geometry. The anion and solvent are engaged in weak O—H...O hydrogen bonds. Of the four triphenyl­phosphane ligands, two each have an equally disordered phenyl ring while the AgI atom is disordered over two positions in a 0.9595 (15):0.0405 (15) ratio and the trifluoro­acetate anion is equally disordered over two positions with respect to the lattice ethanol mol­ecule.

The AgI atom in the title hydrated solvated salt, [Ag(C18H15As)4](CF3CO2)·0.5CH3OH·0.5H2O, is coordinated by four As atoms from triphenyl­arsane ligands in a distorted tetra­hedral geometry. In the crystal, O—H...O hydrogen bonding occurs between carboxyl­ate groups of anions and lattice solvent mol­ecules. Of the four triphenyl­arsane ligands in the Ag complex cation, two each have an equally disordered phenyl ring while the trifluoro­acetate anion is disordered over two positions with respect to the lattice methanol and water mol­ecules which both show half-occupyncy. The crystal studied was a non-merohedral twin with a 13.6 (1)% contribution of the minor twin component.

The AgI atom in the title centrosymmetric dinuclear compound, [Ag2(C11H10N3O)2(C11H11N3O)2]·2H2O, shows a T-shaped coordination arising from bonding to the N atom of a neutral 2-[(pyrimidin-2-yl)amino­meth­yl]phenol ligand, the N atom of the 2-[(pyrimidin-2-yl)amino­meth­yl]phenolate anion [N—Ag—N = 171.8 (1)°] and the terminal O atom of the other anion [Ag—O = 2.606 (3) Å]. A pair of 2-[(pyrimidin-2-yl)amino­meth­yl]phenolate anions link the two AgI atoms to form the dinuclear compound. In the crystal, adjacent dinuclear mol­ecules are linked to the lattice water mol­ecules, generating an O—H...O- and N—H...O-connected three-dimensional network. In the crystal, the hy­droxy H atom is disordered over two positions in a 1:1 ratio; one half-occupancy H atom is connected to one hy­droxy group, whereas the other half-occupancy H atom is connected to another hy­droxy group.

The title coordination polymer, {[Ag2(C6H5N2O)(C6H6N2O)2]NO3}n, features a deprotonated N-(pyridin-4-yl­methyl­idene)hy­droxy­laminate anion and two neutral N-(pyridin-4-yl­methyl­idene)hydroxyl­amine mol­ecules in the asymmetric unit. The anion connects three AgI atoms through its O and two N-donor atoms. One neutral ligand functions in a monodentate mode; the other functions in a bridging mode, binding though its two N atoms. The coordination geometry of the two independent metal atoms is T-shaped; the manner of bridging gives rise to a layer motif parallel to (100). In the crystal, the nitrate ion is disordered over two positions in a 1:1 ratio, and is sandwiched between adjacent layers. O—H...O hydrogen bonding is present between nitrate ions and layers, and also between adjacent layers.

In the mononuclear title compound, [Ag(NO3)(C6H6N2O)2], the AgI atom is located on a twofold rotation axis and the nitrate-chelated AgI atom is further coordinated by two aromatic N atoms of hydroxyl­amine ligands in a distorted tetra­hedral geometry.

The tetra­nuclear title compound, [Sn4(CH3)8(C2H5O)2O2(C3H4N3S)2], lies about a center of inversion; the mol­ecule features a three-rung-staircase Sn4O4 core in which two SnIV atoms are bridged by the 4-methyl-5-sulfanyl­idene-4,5-dihydro-1H-1,2,4-triazol-1-ide group.

The terminal SnIV atom is five-coordinate in a cis-C2SnNO2 trigonal–bipyramidal geometry [C—Sn—C = 127.5 (2)°], whereas the central SnIV atom is six-coordinate in a C2SnNO3 skew-trazepoidal bipyramidal geometry [C—Sn—C = 145.0 (2)°].

In the crystal of the title compound, [Cd2Na2(C2H3O2)2(C21H24N2O4)2]·0.67C2H6O, the doubly deprotonated Schiff base ligand N,N′,O,O′-chelates to the CdII cation, which is also O,O′-chelated by the acetate ion. Two Cd–Schiff base units are connected to two Na+ atoms to form the tetra­nuclear complex, in which the Cd2+ and Na+ cations show distorted octa­hedral coordinations. The asymmetric unit consists of half a tetra­nuclear mol­ecule (lying on an inversion center) and a full tetra­nuclear mol­ecule (lying on a general position) along with a lattice ethanol mol­ecule, which links to the coordinating acetate ion via an O—H...O hydrogen bond. In the crystal, the propyl and ethyl groups of the complex mol­ecule are disordered over two positions in a 1:1 ratio; the ethyl group of the lattice ethanol mol­ecule is also equally disordered over two positions.

In the title compound, [Sn2(CH3)6(NCS)2(C24H22N4)], the 1,2,3,4-tetra­kis­(pyridin-4-yl)butane ligand uses the pyridine N atoms at the ends of the butyl chain to coordinate to two trimethylthiocyanatotin(IV) units, forming a dinuclear structure. The SnIV atom in the mol­ecule shows a distorted trans-trigonal–bipyramidal coordination with the methyl groups in equatorial positions. The mol­ecule lies on a center of inversion, with the mid-point of the butyl chain coinciding with this symmetry element. In the crystal, weak C—H...π inter­actions occur between pyridine rings of adjacent mol­ecules.

In the title compound, C15H14N2O2S, the central C2N2OS moiety is planar (r.m.s. deviation of fitted atoms = 0.0336 Å). This is ascribed to the formation of an S(6) loop stabilized by an intra­molecular N—H...O hydrogen bond; additional intramolecular N—H...O and C—H...S contacts are also noted. The dihedral angles between the central unit and the phenyl and benzene rings are 23.79 (7) and 29.52 (5)°, respectively. The thione S and ketone O atoms are mutually anti, as are the N—H H atoms; the O atoms lie to the same side of the mol­ecule. Centrosymmetric eight-membered {...HNC=S}2 synthons feature in the crystal packing. The resulting inversion dimers stack along the a axis and are connected into a three-dimensional structure by C—H...O and C—H...π inter­actions.

In the title hemisolvate, C14H11ClN2OS·0.5CH2Cl2, an anti disposition is found for the thione and ketone atoms, as well as the N—H H atoms; the dichloro­methane C atom lies on a twofold axis. The central chromophore (including the two adjacent ipso C atoms) is planar (r.m.s. deviation = 0.021 Å) owing to the presence of an intra­molecular N—H...O hydrogen bond, which closes an S(6) loop. Significant twists are evident in the mol­ecule, the dihedral angles between the central moiety and the phenyl and benzene rings being 29.52 (7) and 40.02 (7)°, respectively. In the crystal, eight-membered {...HNC= S}2 synthons with twofold symmetry form via N—H...S hydrogen bonds. The dimers are connected into a supra­molecular chain along [111] by C—H...O inter­actions. The chains stack along the c axis, forming columns which define channels in which the occluded dichloro­methane mol­ecules reside.
