%X cis -[ MoOS (C5H10NO)2] reacts with cyanide in CDCl3 solution to produce cis -[MoO2(C5H10NO)2](50-60%) and SCN- (65-85%). Free C5H10NH and C5H10NOH are formed as well, these results suggesting piperidine N- oxido  ligand as the source of oxidizing equivalents in the system. Under the same conditions, cis -[MoS2(C5H10NO)2] and cis -[ MoOSe (C5H10NO)2] also form cis - [MoO2(C5H10NO)2]. The molecular structure of the title compound reveals Mo-Se and Mo-O ( oxo ) bond lengths of 2.299(1) and 1.719(4) &#506;, and an O-Mo-Se bond angle of 115.3(1)&#176;. The structure is related closely to that of [ MoOS (C5H10NO)2], and detailed differences are those expected for substitution of a thio  ligand by the larger seleno congener. Crystal data: a 6.977(1), b 21.469(3), c 9.791(2) &#506;, &#946; 91.50(2)&#176;; P21/n; Z 4.
