Abstract

Crystals of the title compound, [Cu(2)(C(10)H(9)NO(3))(2)(H(2)O)(2)].2CH(4)N(2)O, consist of two (N-salicylidene-beta-alaninato-kappa(3)O,N,O')copper(II) coordination units bridged by two water moieties to form a dimer residing on a crystallographic inversion center, along with two uncoordinated urea molecules. The Cu(II) atom has square-pyramidal coordination, with three donor atoms of the tridentate Schiff base and an O atom of the bridging aqua ligand in the basal plane. The axial position is occupied by the second bridging water ligand at a distance of 2.5941 (18) A. Hydrogen bonds between molecules of urea and the neighboring dimer units lead to the formation of a two-dimensional grid of molecules parallel to [101]. The superposition of the normals of the pyramidal base planes in the direction [100] indicates possible pi-pi interactions between the neighboring units.
