(μ-3,4-Diacetylhexa-2,4-diene-2,5-diolato-κ4O2,O3:O4,O5)bis[aqua(1,10-phenanthroline-κ2N,N′)copper(II)] bis(tetrafluoridoborate) monohydrate

Abstract

In the title compound, [Cu2(C10H12O4)(C12H8N2)2(H2O)2](BF4)2·H2O, the two Cu atoms are each chelated by the acetylacetonate unit of the 3,4-diacetylhexa-2,4-diene-2,5-diolate (tae) ligand. The Cu atoms are square-pyramidally pentacoordinated, with one bidentate 1,10-phenanthroline (phen) and the tae ligand basal and one water molecule apical. The pyridyl rings of the phen ligands participate in π–π [centroid–centroid distance = 3.894 (3) Å] and C—H ... π interactions, generating layers which are interconnected through O—H...O and O—H...F hydrogen bonds between the water molecules and the tetrafluoridoborate anions. The F atoms of both tetrafluoridoborate anions are each disordered over two positions of equal occupancy.
