trans-Diaquabis(N,N-diethylnicotinamide-N¹)bis(4-nitrobenzoato-O)copper(II)

The title molecule is a crystallographically centrosymmetric mononuclear complex, containing two water molecules, two 4-nitrobenzoato and two diethylnicotinamide ligands, [Cu(C₇H₄NO₄)₂(C₁₀H₁₄N₂O)₂(H₂O)₂], all acting as monodentate ligands. The N and O atoms around the Cu atom form a square-planar arrangement, with the slightly tetragonally distorted octahedral coordination completed by two water O atoms at a distance of 2.485 (2) Å. The water molecules are hydrogen bonded to the carboxyl O atoms [O...O 2.705 (4) Å].
