d]cycloheptenylidene; f, 9-thioxanthenylidene; and g, 2,5-dimethyl-3,4-diphenylcyclopentadienylidene) were prepared along with their gold(I) chloride complexes (R2═CH—NC—AuCl, 5a–f). A comprehensive study of the properties of the precursors, free ligands, and gold(I) complexes is reported and complemented by DFT calculations. Solid-state structure of two complexes (5a and 5c) show extensive aurophilic
为isocyanofulvenes合成两种方法被报告,和一系列的类型R的配体的2 = CH-NC(图4a -克,R 2 =一个,9-亚芴基; b,9-(2,7- dioctyloxylfluorenylidene); c,9-(3,6-二甲氧基芴基亚基); d,9-(3,6-二辛基芴基亚基); e,5-二苯并[ a,d ]环庚烯基;f,9-噻吨亚蒽基;以及g,2,5-二甲基-3,4- diphenylcyclopentadienylidene)与他们的金(I)氯化物复合物(R制备沿2 = CH-NC-AUCL,5A - ˚F)。报告了对前体,游离配体和金(I)配合物的性质的全面研究,并通过DFT计算进行了补充。两个复合物(5a和5c)的固态结构显示出广泛的亲亲相互作用和配体的π-π堆积。金属中心不参与光学过渡。然而,金属配位导致吸收光谱中一致的红移,这表明异氰基与配体的π-系统之间有效的共
