Abstract

The synthesis of mixed halo-phosphine isocyanide complexes of general formula [ReCl2(CNR)₃(PMePh₂)2] ⁺ is described. The crystal structure of a representative member of this class, [ReCl₂(CN-t-Bu)₃(PMePh₂)2](SbF₆) (1), has been determined. This complex adopts the C_2v capped trigonal prismatic geometry with close nonbonded contacts of 2.341 (8) and 2.330 (9) Å between coordinated isocyanide carbon atoms. Such distances in seven-coordinate compounds reveal that they are good candidates for reductive coupling of the isocyanide ligands, a reaction previously studied for 1. The syntheses of [ReCI₃(CN-t-Bu)2(PMePh₂)2] and [ReCl₃(CN-2,6-Me₂Ph)₃(PMePh₂)] are also reported. Red crystals of [Re(O)(OEt)Cl₂(PMePh₂)₂] (2) were isolated in 25% yield as a side product during the preparation of [ReCl₃(PMePh₂)₃] starting material from AgReO₄. The identity of 2 was established by IR spectroscopy, elemental analysis, and X-ray crystallography. The Re-O bond distance of 1.699 (5) Å is characteristic of a metal-oxygen triple bond. Crystal data: for.
