Abstract

The title complex, [Cu(C21H38N5Si)(C18H15P)], was obtained from the one-pot reaction between (Dipp)N(Li)SiMe3 (Dipp = 2,6-diiso-propyl-phen-yl), Me2NCN, CuCl and PPh3. The Cu(I) atom has a distorted trigonal-planar coordination sphere. The tri-aza-penta-dienyl ligand acts as a κ(2)-donor. The N-Cu-N bond angle is 95.88 (14)°. In the tri-aza-penta-dienyl 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.

摘要

标题配合物[Cu(C₂₁H₃₈N₅Si)(C₁₈H₁₅P)]是由(Dipp)N(Li)SiMe₃（Dipp = 2,6-二异丙基苯基）、Me₂NCN、CuCl和PPh₃通过一锅法反应得到的。Cu(I)原子具有一个扭曲的三角平面配位球。三氮杂戊二烯基配体作为一个κ(2)-供体。N-Cu-N键角为95.88 (14)°。在三氮杂戊二烯基片段中，C-N键长在1.328 (5)-1.349 (5) Å范围内，这表明在NCNCN体系中π电子发生了离域。
