The complex of [Zn (bipy) 3] 2 · 4Cl · 5H2O (bipy = 2, 2 ’bipyridyl) was synthesized and its structure was confirmed by X-ray diffractometry.The complex belongs to monoclinic system with space group Cc , The unit cell parameters are a = 1.36 10 (2) (nm), b = 2.54 4 (5) (nm), c = 2.3775 (4) (°), V = 7.0 2 0 0 (2) (nm3), Fw = 12 99.92, Dc = 1.2 20 g cm 3, Z = 4, μ = 0.886 mm -1, F 0 0 0) = 2 6 4 0. The complex crystals of zinc and bipyridine every two ions form an asymmetric unit, Cl -, H 2 O in a state of disorder.
