The trinuclear Mo cluster [Mo3(μ3-X)(μ2-Se2)3{S2P-(OEt)2}3]Cl (X=0.65S+0.35Se) (1) has been synthesised by reacting MoCl3·3H2O with ZnSe and [Me4N][S2P(OEt)2] in an EtOH/HCl medium. Reduction of (1) by Ph3P in the presence of [Me4N]-[S2P(OEt)2] and pyridine gave [Mo3(μ3-X)(μ2-Se)3 {S2P(OEt)2}4(py)]...

Description
Summary:The trinuclear Mo cluster [Mo3(μ3-X)(μ2-Se2)3{S2P-(OEt)2}3]Cl (X=0.65S+0.35Se) (1) has been synthesised by reacting MoCl3·3H2O with ZnSe and [Me4N][S2P(OEt)2] in an EtOH/HCl medium. Reduction of (1) by Ph3P in the presence of [Me4N]-[S2P(OEt)2] and pyridine gave [Mo3(μ3-X)(μ2-Se)3 {S2P(OEt)2}4(py)] (X=0.65S+0.35Se, py=C5H5N) (2). Complex (2) was, in turn, converted into [Mo3(μ3-X)(μ2-SeS)3{S2P(OEt)2}3]I (X=0.65S+0.35Se) (3) by treatment with H2S and I2. The structures of complexes (1), (2) and (3) were established by X-ray crystallography.[PUBLICATION ABSTRACT]
