The title complex, [Ni(C18H12N2O3)(C5H5N)], has a slightly distorted square-planar coordination of the Ni atom with trans N atoms [Ni—N = 1.902 (2) and 2.002 (2) Å, Ni—O = 1.880 (2) and 1.927 (2) Å, N—Ni—N = 171.30 (9)° and O—Ni—O = 173.87 (8)°]. The 2-hydroxybenzoyl hydroxy group forms an intramolecular O—H
N hydrogen bond with an adjacent N atom [NO = 2.591 (3) Å]. Inversion-related molecules have short NiN separations of 3.274 (3) and 3.489 (3) Å, and exhibit concomitant π–π stacking; the centroid of the benzoyl ring is some 3.34 Å from the naphthalene plane of the inversion-related molecule.

The title complex, [K(C14H20O5)2]2[Zn(C3S5)2] or [K(B-15-C-5)2]2[Zn(dmit)2] (B-15-C-5 = benzo15-crown-5 and dmit = 4,5-dimercapto-1,3-dithiole-2-thione), contains two {[K(B-15-C-5)2]2}+ complex cations and one [Zn(dmit)2]2− complex anion in the asymmetric unit. The complex has a three-dimensional network structure assembled by intermolecular SS and weak C—HS interactions.

In the title complex, [Cu(C12H12N2O3)(C5H5N)], the CuII atom has a square-planar coordination geometry, formed by the tridentate hydrazone and the monodentate pyridine ligands. The distance of 3.706 (4) Å between the centroids of the nearly parallel [dihedral angle 4.9 (5)°] pyridine ring and the benzene ring of a neighbouring complex molecule suggests the existence of π–π stacking.

The title compound, [K(C14H20O5)2][Ni(C3S5)2] or [K(benzo-15-crown-5)2][Ni(dmit)2], consists of KI complex cations with benzo-15-crown-5 ligands and NiIII complex anions with 4,5-dimercapto-1,3-dithiole-2-thione (dmit) ligands. The NiIII atom is coordinated by four S atoms from two dmit ligands in a distorted square-planar geometry, while the K+ cation is coordinated by ten O atoms from two crown ether ligands.

The title polymeric complex, [PbPd(NCS)4(C20H36O6)(H2O)]n or {[Pb(DC18C6-A)(H2O)][Pd(SCN)4]}n (DC18C6-A = cis-syn-cis-dicyclohexyl-18-crown-6), has been synthesized by the reaction of dicyclohexyl-18-crown-6 with PdCl2 and Pb(SCN)2. The SCN groups bridge [Pb(DC18C6-A)(H2O)]2+ complex cations and [Pd(SCN)4]2− complex anions to form infinite polymeric chains.

The title binuclear manganese(II) complex, [Mn2(C2H3O2)2(C12H8N2)4](ClO4)2, has been synthesized by the reaction of manganese(II) acetate and tetra-n-butylammonium manganate(VII) with 1,10-phenanthroline in a mixed solvent of acetic acid, ethanol and pyridine. In the centrosymmetric cation, the two MnII atoms are linked to each other by the four O atoms of two acetate ions. Each MnII atom adopts a six-coordinate geometry and the six coordinating atoms form a distorted octahedron.

The title complex, {[Mn(C7H3NO4)(C12H8N2)]·H2O}n, conventionally abbreviated to {[Mn(2,3-pddc)(phen)]·H2O}n (phen is 1,10-phenanthroline and 2,3-pddc is 2,3-pyridinedicarboxylate), has been synthesized under hydrothermal conditions. In the complex, the Mn atom is coordinated by three O atoms of three symmetry-equivalent 2,3-pddc molecules. The complex thus extends in two dimensions, resulting in the formation of a two-dimensional network structure. The complex is further assembled into a three-dimensional network by π–π stacking interactions involving the phen ligands.

In the binuclear title manganese(II) complex, [Mn2(C2H3O2)2(C10H8N2)4](ClO4)2, the Mn atoms are six-coordinate in a distorted octahedral coordination geometry. The two Mn atoms are bridged by two acetate groups to form a dimeric cation. The complex forms chains through π–π stacking interactions.

The title mononickeladodecaborane cluster, [NiB11H6(OC3H7)5(H2O)2], has been synthesized by the reaction of dichlorobis(triphenylphosphine)nickel(II) with triethylammonium nido-undecaborane(14) in 2-propanol. The NiIV atom is connected to five atoms of the boron cage to form a closo 12-vertex {NiB11} icosahedral skeleton. All of the H atoms on the five B cage atoms connected to the Ni atom are substituted by isopropoxy groups. The NiIV atom is also bonded to two water molecules. The molecules form dimers through intermolecular hydrogen-bond interactions.

The title cluster, [Ru(C7H11B10ClN2O6)(C2H3N)(C18H15P)] or [1,2-{3,5-(NO2)2(C6H3)COO}-1-(PPh3)-1-(CH3CN)-3-Cl-1-RuB10H8], has an iso-closo 11-vertex RuB10 core geometry with the metal occupying the unique six-connected apical position, giving the characteristic 11-vertex iso-closo [MB10] metalloborane 1:2:4:2:2 stack. The ruthenium centre has three exo-polyhedral ligands: one triphenylphosphine, one acetonitrile and one 3,5-dinitrobenzoate, which is coordinated through Ru—O and B—O bonds, resulting in an exocyclic five-membered Ru/O/C/O/B ring.

The approximately planar molecule of the title compound, C14H13N3O3, is in an E configuration with respect to the C=N bond, with a C—C=N—N torsion angle of −177.3 (2)°. There is an intramolecular hydrogen bond involving the hydrazide N atom and the hydroxyl O atom on the benzene ring. Intermolecular C—HO weak interactions are also formed between two adjacent methoxy groups, linking two molecules into a coplanar dimer. These dimers are further assembled into a zigzag framework along the [010] axis, using intermolecular short C—HO and long N—HO hydrogen bonds, resulting in a two-dimensional supramolecular crystal structure.
