Synopsis: In two dinuclear copper complexes, the two CuII ions are bridged by four syn,syn-1:1: carboxylate groups, showing a paddle-wheel cage type structure with a square-pyramidal geometry. The three-dimensional supramolecular metal-organic frameworks of one complex consist of three different (20) and an (36) ring motif, while the other complex simply packs as molecular species.
Formula: [Cu2(C7H5O3)4(H2O)2]·2C3H7NO·2H2O and an analogue
