The neutral complexes [Cr(CO)4(Ph2AsOAsPh2)] 1, [Mo(CO)4(Ph2AsOAsPh2)2] 2, [Cr(CO)4(Ph2AsSAsPh2)] 3, [Mo(CO)4(Ph2AsSAsPh2)2] 4, [Cr(CO)5(Ph2AsOAsPh2)] 5 and [Cr(CO)5(Ph2AsSAsPh2)] 6 have been prepared. The crystal structures of compounds 1–5 were determined. The diarsenic ligand in 2, 4, and 5 is monodentate and in 1 and 3 the ligand is bidentate. The crystal structure of the ligand Ph2AsOAsPh2 was
中性络合物[Cr(CO)4(Ph 2 AsOAsPh 2)] 1, [Mo(CO)4(Ph 2 AsOAsPh 2)2 ] 2, [Cr(CO)4(Ph 2 AsSAsPh 2)] 3, [ Mo(CO)4(Ph 2 AsSAsPh 2)2 ] , [Cr(CO)5(Ph 2 AsOAsPh 2)] 5和[Cr(CO)5(Ph 2 AsSAsPh 2)] 6已经准备好了。确定了化合物1-5的晶体结构。砷配体在2,4和5是单齿和在1和3的配体是双齿的。的晶体结构配体重新确定了Ph 2 AsOAsPh 2,发现As–O–As角为115.98(17)°,大大小于最初报告的值。使用密度泛函理论的计算有助于讨论影响结合模式选择的空间和电子因素。
