(Received 4 March 2009; accepted 4 March 2009; online 25 March 2009)

The water-coordinated metal atom in the title compound, [Cu(C₇H₄NO₄)₂(C₆H₆N₂O)₂(H₂O)₂], lies on a center of inversion in an all-trans octahedral environment with slight distortions. The molecule interacts with adjacent molecules through O—H⋯O and N—H⋯O hydrogen bonds, forming a layered network parallel to (010).

Experimental top

A water/methanol (1:1 v/v) solution (3 ml) of copper nitrate trihydrate (0.174 g, 0.6 mmol) was added to a water/methanol (1:1 v/v) solution (3 ml) of 2-nitrobenzoic acid (0.100 g, 0.6 mmol), sodium hydroxide (0.024 g 0.6 mmol) and nicotinamide (0.073 g, 0.6 mmol). Blue block were obtained after several days (yield: 40%). CH&N elemental analysis: calc. for C₂₆H₂₄CuN₆O_12: C 46.19, H 3.59,N 12.43%; found: C 46.37, H 3.41, N 12.60%.
