Microwave studies (26.5-40 GHz) of further isotopic species of selenoketene formed by pyrolysis of 1,2,3-selenodiazole (12CH2 12C76,77,82Se, 12CH2 13C80Se and 13CH2 12C80Se) and by pyrolysis of 5-deuterio-1,2,3-selenodiazole (12CHD12C78,80Se) are reported. In conjunction with earlier results for 12CH12C78,80Se an rs structure has been derived with distances SeC (1.706 Å), CC (1.303 Å), CH (1.0908 A) and a HCH bond angle of 119.7°. The geometry of the CH2C moiety of selenoketene is closer to allene, CH2CCH2, than to ketene, CH2CO.
