Addition of NH2OH to the reaction mixtures results in the formation of nitrosyl complexes containing either the Mo(NO)3 or the Mo(NO) 2 2 units. The amidoxime component may be present either as RC(NH2)NHO. RC(NHi2), RC(NH)NHO or RC(NH)NO2: ligands, or as hydrogen-bonded RC(NH2)NOH molecules. The crystal structures of [MoO(acac)RIC'(NH2)NO] {RJC(NH)NO}](1), [Mo(NO)(acae)2 {RIC(NH2)NO}] (4), (NBu4)2[Mo4O10(OMe)2{RIC(NH) NO}2] (12a),(NBu4)2(H3O)[Mo5O13(OMe)4(NO)].2R1C(NH2)NOH(13b) and [R1C(NH2)2)]3[Mo5O13(OEt)4(NO)] (14) (R1=2-thienyl) are reported. The cryslallographic data for these compounds are as follows:1, mono-clinic. P21 a.a=24.547(4)A. b=8.188(4)A. c=9.607(3)A, ß=96.18(3)c, R=0.046.
