Bis(?-naphthalene-1,8-dicarboxyl-ato-?O:O)bis-[aqua-bis-(N,N'-dimethyl-formamide-?O)copper(II)].

ABSTRACT: In the centrosymmetric dinuclear title complex, [Cu(2)(C(12)H(6)O(4))(2)(C(3)H(7)NO)(4)(H(2)O)(2)], the coordination environment of each Cu(II) atom displays a distorted CuO(5) square-pyramidal geometry, which is formed by two carboxyl-ate O atoms of two ?-1,8-nap ligands (1,8-nap is naphthalene-1,8-dicarboxyl-ate), two O atoms of two DMF (DMF is N,N'-dimethyl-formamide) and one coordinated water mol-ecule. The Cu-O distances involving the four O atoms in the square plane are in the range 1.9501?(11)-1.9677?(11)?Å, with the Cu atom lying nearly in the plane [deviation = 0.0726?(2)?Å]. The axial O atom occupies the peak position with a Cu-O distance of 2.885?(12)?Å, which is significantly longer than the rest of the Cu-O distances. Each 1,8-nap ligand acts as bridge, linking two Cu(II) atoms into a dinuclear structure. Inter-molecular O-H?O and C-H?O hydrogen-bonding inter-actions consolidate the structure.
