Bis{2-[(1H-pyrrol-2-yl)methyl-imino-meth-yl]phenolato-κN,O}zinc(II).

ABSTRACT: In the title compound, [Zn(C(12)H(11)N(2)O)(2)], the Zn(II) atom, lying on an inversion center, is coordinated by two O atoms and two N atoms from two salicylal Schiff base ligands in a distorted square-planar geometry. A three-dimensional network is formed by inter-molecular C-H⋯N hydrogen bonds and C-H⋯π contacts.

Bis{?-2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}bis-({2-meth-oxy-6-[(methyl-imino)-meth-yl]phenolato}copper(II)).

Project description:The title compound, [Cu2(C9H10NO2)4], is built of discrete centrosymmetric dimers. The Cu(II) atoms are each five coordinated by two deprotonated Schiff base ligands that are bonded differently to the metal atoms. Of the two phenolate O atoms, one is coordinated to one Cu(II) atom, whereas another bridges the two metal atoms. The basal plane of the square pyramid around Cu(II) atoms is formed by the imino N and phenolate O atoms of the bidentate and the monodentate/bidentate Schiff base ligands. The bridging phenolate oxygen occupies the apical position of the coordination sphere with a considerably longer Cu-O bond length. In the crystal, the dimeric mol-ecules pack relative to each other in such a way that the Cu2O2 planes of adjacent dimers are orthogonal.
