Bis(4-aminopyridinium) bis(oxalato-²O,O')cuprate(II) dihydrate

Z.-C. Pan, K.-L. Zhang and S. W. Ng

Abstract: The Cu^II atom in the title salt, (C₅H₇N₂)₂[Cu(C₂O₄)₂]·2H₂O, is located on a center of inversion and is chelated by two oxalate groups in a square-planar coordination geometry. The cation, anion and water molecules interact through hydrogen bonds, forming a three-dimensional hydrogen-bonded network.
