چکیده
In the title compound, [Cu(2)(C(15)H(12)N(2)O(4))(2)(C(6)H(5)N)(2)], each Cu(II) atom is chelated by the tridentate doubly deprotonated Schiff base and a pyridine mol-ecule in a nearly planar environment (r.m.s. deviation for all non-H atoms = 0.107 Å). The metal ions are bridged by one O atom from the symmetry-related Schiff base ligands, forming a centrosymmetric dinuclear copper(II) complex. The dimeric complex is linked to another dimer via weaker Cu-O inter-actions and also O-H⋯N hydrogen bonds.

The metal atom in the title compound, [Cd(C(15)H(13)N(2)O(4))(2)]·2C(2)H(6)OS, is twice O,N,O'-chelated by two symmetry-related Schiff base ligands to define a trans-N(2)O(4) octa-hedral geometry. Each anion occupies meridional sites of the octa-hedron; the metal atom lies on a special position of site symmetry 2. The dimethyl sulfoxide mol-ecule is a hydrogen-bond acceptor to the -NH- unit, an...

In the crystal structure of the title centrosymmetric dimer, [Cu(2)(C(17)H(14)N(2)O(2))(2)(C(5)H(5)N)(2)], the Cu(II) atom has an almost perfect square-pyramidal geometry. The Cu(II) ion is coordin-ated by the NO(2) donor atoms of the hydrazide Schiff base ligand, the N atom of the pyridine group and an O atom of the symmetry-related unit. The dihedral angles between the pyridine ring and the t...

The crystal structure of the title complex, [Cu(2)(C(15)H(10)Cl(2)N(2)O(2))(2)(C(5)H(5)N)(2)], features centrosymmetric dimers. The Cu(II) ion is penta-coordinated in a quadratic pyramidal mode. The quadratic plane is formed by the O,O',N-tridentate ligand and a pyridine mol-ecule. The fifth coordination site is occupied by the O atom of another ligand showing a significantly longer Cu-O bond.
