Abstract trans-Diaquabis(2-benzoylpyridine)copper(II) nitrate has been prepared and characterized by spectroscopic methods and X-ray crystallography. The complex exhibits strong infrared carbonyl absorption at 1655 cm−1 and a broad d-d band centered about 14,090 cm−1. The crystals are monoclinic, space groupP21/c witha=7.872(1),b=14.573(3),c=11.132(1) Å,β=102.79(1)°,Z=2, andR F =0.049 for 2440 observedMo-Kα reflections. The crystal structure consists of a packing of centrosymmetric [Cu(2-benzoylpyridine)2(H2O)2]2+ cations and nitrate ions, which are interlinked by hydrogen bonds to form thick layers corresponding to the (100) family of planes. The coordination geometry about the copper atom is an elongated octahedron with aqua ligands occupying the axial positions. The measured bond distances are: Cu-O(aqua)=2.256(3), Cu-O(L)=2.068(2), and Cu-N=1.965(2) Å.
