Homoleptic selenium cyanides: Attempted preparation of Se(CN)4 and redetermination of the crystal structure of Se(CN)2
The preparation of Se(CN)4 was attempted by the reaction of SeF4 with Me3SiCN at low temperatures. However, selenium tetracyanide could not be detected by NMR spectroscopy; instead, the decomposition product Se(CN)2/
