The chemistry of the bidentate (S,S–) donor ligands 2-aminocyclopent-1-ene-1-carbodithioic acid (HL1) and its N-alkylated derivatives [alkyl = C2H5(HL2), C4H9(HL3), or cyclo-C6H11(HL4)] with molybdenum in oxidation states +6 and +5 is described. The MoVI compounds are all cis-dioxo-species. Reduction of [MoO2(L1)2] with excess HL1 yields [MoO(L1)3], a monomeric MoV compound. The complexes are all intensely
二齿(S,S –)供体配体2-氨基环戊-1-烯-1-碳二硫代酸(HL 1)及其N-烷基化衍生物的化学组成[烷基= C 2 H 5(HL 2),C 4 H描述了具有在+6和+5氧化态的钼的图9(HL 3)或环-C 6 H 11(HL 4)]。Mo VI化合物都是顺式-二氧杂种。用过量的HL 1还原[MoO 2(L 1)2 ]产生[MoO(L 1)3 ],单体Mo V化合物。由于配体到金属的电荷转移跃迁,这些复合物都被强烈着色。描述了这些复合物的红外电子,静电,电磁和电化学研究。根据电子结构及其与黄嘌呤氧化酶中Mo中心的关系来讨论结果。
