Tetraamminebis(pyrazine-2-carboxylato-N⁴)copper(II)

S.-W. Peng, Y.-L. Miao and W.-D. Song

Abstract: In the title complex, [Cu(C₅H₃N₂O₂)₂(NH₃)₄], the Cu^II atom lies on a site of symmetry 2/m and has distorted elongated octahedral coordination geometry defined by four N atoms from ammonia molecules and another two N atoms from two pyrazine-2-carboxylate ligands. The crystal packing is governed by intermolecular N-HO and C-HO hydrogen bonds.
