(μ-3,4-Diacetyl­hexa-2,4-diene-2,5-diol­ato-κ(4) O (2),O (3):O (4),O (5))bis­[aqua(1,10-phen­an­thro­line-κ(2) N,N′)copper(II)] bis­(tetra­fluorid­oborate) monohydrate

In the title compound, [Cu(2)(C(10)H(12)O(4))(C(12)H(8)N(2))(2)(H(2)O)(2)](BF(4))(2)·H(2)O, 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.
