ABSTRACT: In the mononuclear title compound, [Co(III)(C(15)H(12)N(2)O(3))(C(5)H(5)N)(3)]ClO(4), the Co(III) ion is coordinated by three pyridine mol-ecules and one N'-(3-meth-oxy-2-oxidobenzyl-idene)benzohydrazidate Schiff base ligand in an O,N,O'-tridentate manner. The Co(III) ion adopts a distorted CoN(4)O(2) octa-hedral coordination environment.

Project description: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) units are linked by π-π inter-actions between adjacent pyridine mol-ecules, with a centroid-centroid distance of 3.724 Å, resulting in a two-dimensional structure.
