Trinuclear metallacyclic oxidovanadium(V) complexes, [{VO(LR)}] (-) with asymmetric multidentate linking ligands (HLR: R = H, Me, Br), were synthesized. The molecular structure of is characterized as a tripod structure, with each V(V) ion coordinated by -atoms from a tridentate Schiff base site and -atoms from a bidentate benzoxazole site of two respective HLH ligands. The intramolecular V⋯V distances range from 8.0683 to 8.1791 Å. Complex is a mononuclear dioxidovanadium(V) complex, (EtNH)[VO(HLH)]. Cyclic voltammograms of - in DMF revealed redox couples attributed to three single-electron transfer processes.
合成了具有不对称多齿连接配体（HLR：R = H、Me、Br）的三核金属环氧化钒（V）配合物[{VO(LR)}] (-)。其分子结构被表征为三脚架结构，每个V(V)离子由来自两个各自的HLH配体的三齿席夫碱位点的-原子和来自双齿苯并恶唑位点的-原子配位。分子内V⋯V距离范围为8.0683至8.1791 Å。配合物是单核二氧钒（V）配合物(EtNH)[VO(HLH)]。在DMF中-的循环伏安图显示了归因于三个单电子转移过程的氧化还原对。
