| Description | Crystals of the title compound, [Cu2(C10H9NO3)2(H2O)2].2CH4N2O, consist of two (N-salicylidene-beta-alaninato-kappa3 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 CuII 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. |
