Bis{μ-2-[(pyrimidin-2-yl)amino­meth­yl]phenolato}-κ²N¹:O;κ²O:N¹-bis­({2-[(pyrimidin-2-yl-κN)amino­meth­yl]phenol}silver(I)) dihydrate

The Ag^I 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 Ag^I 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 Ag^I 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.

(Nitrato-κ²O,O′)bis­[(E)-N-(pyridin-4-yl­methyl­idene-κN)hy­droxy­amine]­silver(I)

In the mononuclear title compound, [Ag(NO₃)(C₆H₆N₂O)₂], the Ag^I atom is located on a twofold rotation axis and the nitrate-chelated Ag^I atom is further coordinated by two aromatic N atoms of hydroxyl­amine ligands in a distorted tetra­hedral geometry. In the crystal, the nitrate ion has 2 symmetry with the N atom and one O atom located on the twofold rotation axis, and is linked to hy­droxy groups of the hydroxyl­amine ligands by O—H...O hydrogen bonds, generating a chain running along the b axis.

Tris{2-[(pyrimidin-2-yl-κN)amino­meth­yl]phenol}silver(I) nitrate

The Ag^I atom in the title compound, [Ag(C₁₁H₁₁N₃O)₃]NO₃, shows a T-shaped coordination arising from bonding to the N atom of three N-heterocycles; the geometry is distorted towards square pyramidal owing to two weak Ag...O_nitrate inter­actions [Ag...O = 2.691 (5) and 3.073 (5) Å]. The cation and anion are linked by O—H...N and N—H...O hydrogen bonds, generating a three-dimensional network.

In the centrosymmetric dinuclear title Ag^I compound, [Ag₂(C₆H₆N₂O)₄](NO₃)₂, the aromatic amine-coordinated Ag^I atom is further bridged by two hydroxyl­amine mol­ecules that use aromatic and oxime N atoms for bridging, and it exists in a distorted trigonal-planar geometry. In the crystal, the nitrate anions link to the dinuclear compound mol­ecules via O—H...O hydrogen bonds, generating a chain running along the a-axis direction.
