Crystal structure of [1-(2,6-diiso­propyl­phen­yl)-2,4-bis­(di­methyl­amino)-5-tri­methyl­silyl-1,3,5-tri­aza­penta­dienyl-κ(2) N (1),N (5)](tri­phenyl­phosphane-κP)copper(I)

The title complex, [Cu(C(21)H(38)N(5)Si)(C(18)H(15)P)], was obtained from the one-pot reaction between (Dipp)N(Li)SiMe(3) (Dipp = 2,6-diiso­propyl­phen­yl), Me(2)NCN, CuCl and PPh(3). The Cu(I) atom has a distorted trigonal–planar coordination sphere. The tri­aza­penta­dienyl ligand acts as a κ(2)-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.
