Structural and Magnetic Properties of Dimeric [Ni₂(en)₄Cl₂]Cl₂
Abstract
The crystal structure of dimeric [Ni2(Bn)4Cl2]Cl2 has been determined at ambient temperatures. Crystal data: space group P21/c, Z = 2, a = 6.327 (3) Å, b = 11.311 (2) Å, c = 15.811 (4) Å, β = 117.81°, R = 2.8% for 1530 reflections. The complex consists of chlorine-bridged dimers with unsymmetrical Ni-Cl bridging. The Ni-Cl distances are 2.47 and 2.56 Å, the Ni-Cl-Ni angle is 96.55°, and the coordination octahedron is distorted. The single-crystal magnetic susceptibilities have been determined between 1.5 and 25 K and confirm the earlier report of ferromagnetic intradimer exchange interaction. The parameters resulting are: 〈g〉 = 2.25, D/k = 14 ± 1 K, J/k = 5.0 ± 0.5 K, and zJ′/k = -0.3 ± 0.1 K. © 1979 American Chemical Society.
