چکیده
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)amino-meth-yl]phenol ligand, the N atom of the 2-[(pyrimidin-2-yl)amino-meth-yl]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)amino-meth-yl]phenolate anions link the two Ag(I) atoms to form the dinuclear compound. In the crystal, adjacent dinuclear mol-ecules are linked to the lattice water mol-ecules, generating an O-H⋯O- and N-H⋯O-connected three-dimensional network. In the crystal, the hy-droxy H atom is disordered over two positions in a 1:1 ratio; one half-occupancy H atom is connected to one hy-droxy group, whereas the other half-occupancy H atom is connected to another hy-droxy group.

In the title compound, [Ag(2)(C(14)H(14)N(4))(2)](C(14)H(8)N(2)O(4))·2H(2)O, each of the two unique Ag(+) ions is two-coordinated by two N atoms from two different 1,4-bis-[(imidazol-1-yl)meth-yl]benzene ligands in an almost linear fashion [N-Ag-N = 170.34 (10) and 160.25 (10)°]. The 4,4'-diazenediyldibenzoate anions do not coordinate to Ag. O-H⋯O hydrogen bonds stabilize the crystal structure.

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⋯Onitrate inter-actions [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.

The Ag(I) atom in the polycationic salt, {[Ag(C(11)H(11)N(3)O)]NO(3)}(n), shows a linear coordination [N-Ag-N = 175.0 (2)°]; the polymeric nature arises from bridging by the pyrazine portion of the ligand, resulting in chains extending parallel to [100]. The NO(3) (-) counter-ions surround the polymeric chain and inter-act only weakly with it [Ag⋯O = 2.701 (4) and 2.810 (5) Å]. Adjacent chains ...

In the title centrosymmetric zinc(II) complex, [Zn(2)(C(4)H(13)NO(2))(2)(C(6)H(5)N)(2)], each Zn(II) atom is coordinated by two 2-[(2-oxidobenzyl-idene)amino-meth-yl]phenolate (L) ligands and one pyridine (py) mol-ecule in a distorted trigonal-bipyramidal geometry. Each L ligand behaves as a tridentate ligand and provides a phenolate oxygen bridge which links the two Zn(II) atoms. The ZnL(py) u...
