Crystal and molecular structure of bis(N, N‐dipropyl‐N′‐diphenoxythiophosphoryl‐thioureato) nickel(II) [(C₆H₅O)₂P(S)NC(S)N(C₃H₇)₂]₂Ni

Abstract

Abstract The Ni complex [C 6 H 5 O 2 P(S)N(C 3 H 7 2 ] 2 Ni is monoclinic, space group P2 1 /n with a = 8.890(3), b = 21.692(5), c = 11.670(4) Å, β = 108.35(5)°, V = 2136(1) Å 3 , F(000) = 916, M r = 534.01, Z = 2, D m = 1.318, D x = 1.358 Mg m −3 , graphite monochromatized MoK α − radiation, π = 0.7107 Å, μ = 0.76 mm −1 , T = 293 K. The structure was solved by a heavy atom method and refined to R = 0.044 for 3095 independent reflexions. The Ni atom lies in the centre of symmetry and is coordinated by four S atoms of the two molecules of the ligand in a planar arrangement. NiS bond lengths are 2.205 and 2.226 Å resp., the angles SNiS are 97.65 and 82.35° resp.
