[MoCl3O(thf)2](thf = tetrahydrofuran) with bidentate ligands [L–L = Ph2PCH2CH2PPh2(dppe); Ph2AsCH2CH2AsPh2(dpae); cis-Ph2PCHCHPPh2(dppen); cis-Ph2AsCHCHAsPh2(dpaen) : Ph2AsCH2CH2PPh2(dadpn); cis-Ph2AsCHCHPPh2(dadpen); C6H4(PPh2-o)2(pdpp); and C6H4(AsPh2-o)(PPh2-o)(pdadp)] has led to the isolation of [MoCl3O(L–L)] complexes. Refluxing these complexes in methanol leads to partial reduction to form [Mo
[MoCl 3 O(thf)2 ](thf =四氢呋喃)与双齿配体的反应[L–L = Ph 2 PCH 2 CH 2 PPh 2(dppe); Ph 2 AsCH 2 CH 2 AsPh 2(dpae); 顺式-Ph 2 PCH CHPPh 2(dppen); 顺式-Ph 2 AsCH CHAsPh 2(dpaen):Ph 2 AsCH 2 CH 2 PPh 2(dadpn);顺式-Ph 2 AsCH CHPPh 2(dappen);Ç 6 ħ 4(PPH 2 - ø)2(pdpp); C 6 H 4(AsPh 2 - o)(PPh 2 - o)(pdadp)]导致[MoCl 3 O(L–L)]络合物的分离。在甲醇中回流这些络合物会导致部分还原,形成[Mo IV ClO(L–L)2 ] [Mo V Cl 4 O],但是在存在L–L和Na [BPh 4 ]的情况下在甲醇中回流会完全还原为[MoClO(L–L)2
