Crystal structure of [1-(2,6-diiso-propyl-phen-yl)-2,4-bis-(di-methyl-amino)-5-tri-methyl-silyl-1,3,5-tri-aza-penta-dienyl-κ(2) N (1),N (5)](tri-phenyl-phosphane-κP)copper(I).

Abstract

The title complex, [Cu(C21H38N5Si)(C18H15P)], was obtained from the one-pot reaction between (Dipp)N(Li)SiMe3 (Dipp = 2,6-diiso­propyl­phen­yl), Me2NCN, CuCl and PPh3. The CuI atom has a distorted trigonal–planar coordination sphere. The tri­aza­penta­dienyl ligand acts as a κ2-donor. The N—Cu—N bond angle is 95.88 (14)°. In the tri­aza­penta­dienyl fragment, the C—N bond lengths are in the range 1.328 (5)–1.349 (5) Å, which indicates delocalization of the π-electrons in the NCNCN system.
