The terminal diarsene HAs=AsH ligand attracts special interest concerning its bonding relation in comparison to its isolable relative, ethene. Herein, by the methanolysis of [{Fe(CO) }As(SiMe ) ] (1) the synthesis of [{Fe(CO) }(η -As H )] (2) is reported, containing a parent diarsene as unprecedented side-on coordinated ligand. Following this synthetic route, also the D-labeled complex [{Fe(CO) }(η -As D )] (2D) could be isolated. The electronic structure and bonding situation of 2 was elucidated by DFT calculations revealing that 2 is best described as an olefin-like complex. Moreover, the reactivity of 2 towards the Lewis acids [{M(CO) }(thf)] (M=Cr, W) was investigated, leading to the complexes [Fe(CO) AsHW(CO) ] (3) and [{Fe(CO) } AsH{Cr(CO) }] (4), respectively.

There is considerable interest, from both experimental and theoretical perspectives, in molecules incorporating multiple bonds between main group elements. Herein, we not only consider the parent molecules HE=EH (E=As, Sb, Bi), but also a number of their isomers. For each E H molecule, a number of different structures were optimized with four different DFT methods.
