Synthese und Kristallstruktur von [{(tBu2P)2InCl}2]

Synthesis and Crystal Structure of [{(tBu₂P)₂InCl}₂] The reaction of InCl₃ with tBu₂PSiMe₃ leads to [{(tBu₂P)₂InCl}₂] ( 1 ). 1 crystallizes in the space group P2₁/c. The lattice constants (at 216 K) are: a = 945.9(5) pm, b = 1 604.1(9) pm, c = 1 636.8(8) pm, β = 100.55(4)°. 1 contains a planar In₂P₂ ring. Each In atom is coordinated by two bridging tBu₂P groups, a terminal tBu₂P group and a terminal Cl atom. The coordination geometry of the In atoms is roughly tetrahedral.
