Supra­molecular architecture of metal-organic frameworks involving dinuclear copper paddle-wheel complexes

S. Gomathi and P. T. Muthiah

Synopsis: In two dinuclear copper complexes, the two CuII ions are bridged by four syn,syn-[eta]1:[eta]1:[mu] 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 R_{2}^{2}(20) and an R_{4}^{4}(36) ring motif, while the other complex simply packs as mol­ecular species.

Formula: [Cu2(C7H5O3)4(H2O)2]·2C3H7NO·2H2O and an analogue
