metal-organic compounds
The CuII atom in the title compound, [Cu2(C10H9NO3)2(C4H4N2)].4H2O, adopts a square-pyramidal coordination with the three donor atoms of the N-salicylidene-R, S-alaninato Schiff base dianion and one N atom of the pyrazine ligand bound in the basal plane. The axial position is occupied by a phenolato O atom of a symmetry-related ligand at an apical distance of 2.396 (2) Å. The molecules are connected through the second N atom of the pyrazine to form binuclear copper units, further linked through the above-mentioned apical coordinations into chains parallel to [1 0 0]. The water molecules help to form an hydrogen-bonding network between the chains. All copper polyhedra and the molecular axis are oriented parallel.
