Abstract

Reaction of [Ni(μ-t-Bu₂As)(PMe₃)₂]₂, with I2(Ni:I = 1:2) in toluene yields the black, crystalline Ni(III) complex trans-Nil3(PMe3)2. (1), (38%). The coordination geometry about Ni is a distorted trigonal bipyramid with a distortion which can be attributed to a Jahn-Teller effect. One Ni-I bond (2.530(1)Å) is shorter than the other two (both 2.551(1)Å). Crystal data.(l),C₆H₁₈I₃NiP₂. M = 591.6. orthorhombic, space group Pnma.[formula omittd](graphite monochromator). μ(MoKa) = 70.4 cm-1. Refinement of 1168 reflection formula omittd out of 1667 unique observed reflections (2.0° < Id < 50.0°) gave R and RH values of 0.046 and 0.066. respectively. The Ni-P distances are 2.246(2) A and 2.253(2) Å.
