Abstract

The title complex, [Au(NCO)(CHN)], was synthesized by ligand metathesis from [1,3-bis-(2,6-diiso-propyl-phen-yl)imidazol-2-yl-idene]gold(I) chloride and sodium cyanate in anhydrous tetra-hydro-furan and crystallized from toluene at 233 K in the ortho-rhom-bic space group 222, as a neutral complex with the central Au atom di-coordinated by an -heterocyclic carbene [Au-C = 1.963 (2) Å] and an iso-cyanate [Au-N 1.999 (2) Å] ligands, with a linear CAuNCO moiety. The crystal packing is consolidated by C-H⋯O hydrogen bonds.

摘要

标题配合物[Au(NCO)(CHN)]是通过配体复分解反应，由[1,3-双-(2,6-二异丙基苯基)咪唑-2-亚基]氯化金(I)与氰酸钠在无水四氢呋喃中合成的，并于233 K从甲苯中结晶，属于正交晶系空间群222，是一种中性配合物，中心金原子由一个 - 杂环卡宾[Au-C = 1.963 (2) Å]和一个异氰酸酯[Au-N 1.999 (2) Å]配体双配位，具有线性CAuNCO部分。晶体堆积通过C-H⋯O氢键得以巩固。
