The crystal structure of hydroxyl - bridged dinuclear copper compound [Cu2 (bipy) 2 (OH) 2] (ClO4) 2 (bipy = 2, 2 ’- bipyridine) was prepared and its crystal structure was determined by X - Triclinic system space group C2 / m, α = 1 3.5 69 (3), b = 1 5 .2 1 2 (3), c = 6.2 71 5 (1 0), β = 1 1 3.62 0 The molecular weight of Mr = 672.36, F (0 0 0) = 676.0. The molar ratio of the compound of C18H18Cl2 to Cu2N4O10 can be calculated as follows: V = 1 1 88.4 (4) 3, Dc = 1 .879 g / The structure consisted of one [Cu (bipy) 2 (OH) 2] 2 + cation and two weakly coordinating perchlorates. Two Cu (II) ions in each cation were linked by two hydroxyl bridges, and Cu II) atoms exhibit Cu 4 N 2 square planar configuration with Cu (1) O (3) weakly coordinated bonds of perchlorate in the molecule and O (1) -H (1) A ... O 2) and C (1) - H (1) B ... O (2)
