Coordination of ( N,N-dibenzyl)benzene sulfenamide to pentacarbonylchromium(0) via the sulfur atom. Crystal structure of (C 6H 5CH 2) 2NS(C 6H 5)Cr(CO) 5

Abstract

C 25H 19NO 5Cr; M r = 497.5; triclinic; space group P 1 ; a 11.077(4), b 13.313(5), c 18.486(9) Å, α 108.69(2), β 101.58(3), γ 92.83(2)°; V 2510.7(2) Å 3; Z = 4; D x 1.316 g.cm −3; λ(Cu- K α) 1.5418 Å; μ 48.5 cm −1; F(0,0,0) = 1024; R = 0.060 at room temperature for 3963 unique observed reflections and 596 parameters. There are two independent molecules in the asymmetric unit; the both have enantiomeric configurations at the sulfur atoms, similarly distorted octahedral geometry about the chromium atoms, and sulfur and five carbonyl groups occupying the coordination sites, but they show slightly different spatial arrangements of the aromatic rings in the sulfenamide moiety. For both molecules the CrCO bond distance trans to CrS bond is shorter than the averaged distance for the remaining CrCO bonds.
