Abstract

Abstract (Tri-tert-butoxysilanethiolato)bis(triphenylphosphine)copper(I), which was obtained by reaction of triphenylphosphine with [(t-BuO) 3SiSCu] 4 in benzene, forms colourless plates, with the following crystal data: a=12.772(1), b=18.475(2), c=10.259(1) Å, α=93.38(1), β=106.302(7), γ=90.128(9)°, space group P 1 and Z=2. The structure was refined to an R ( R w) value of 0.0382 (0.0280). The crystal consists of monometallic molecules in which the copper atom is three-fold coordinated to one sulfur and two phosphorus atoms in an essentially trigonal planar arrangement. The relevant bond distances and angles are: CuP 2.292(1), 2.273(1), CuS 2.250(1), SSi 2.074(1) Å; PCuP 123.7(0)°, PCuS 110.2(0), 126.0(0), CuSSi 103.7(1)°
