| 摘 要： | 四唑酸(–CN4H)与羧酸(–COOH)具有相似的酸性。对苯酚四唑硫酮(H2L)可以作为单齿(–S或–N)或双齿(–N, N或–N, S)配体与金属离子配位形成配位化合物。合成了4个以H2L为配体的金属(II)配合物：Co(HL)2(Py)2(H2O)2 (1), Mn(HL)2(H2O)4]·2H2O (2), Mn(HL)2(Phen)2 (3), and Zn(HL)2(Phen)2]·0.5H2O·1.5CH3OH (4)，并用X−射线单晶衍射法测定了晶体结构。晶体结构分析表明，在这些配合物中所有的中心金属原子均呈现六配位的八面体构型。在配合物1和2中，HL–配体以氧原子与中心金属原子配位，而在配合物3和4中HL–配体则以硫原子与中心金属原子配位。

| Abstract: | Tetrazolic acid, CN4H, has similar acidity to carboxylic acid group, COOH. 1‐(4‐Hydroxyphenyl)‐5‐mercaptotetrazole (H2L) can act as a monodentate (S or N) or a bidentate (N, N or N, S) ligand, forming coordination compounds with metal ions. Four new M(II) complexes with HL? ligands, Co(HL)2(Py)2(H2O)2 ( 1 ), Mn(HL)2(H2O)4]·2H2O ( 2 ), Mn(HL)2(Phen)2 ( 3 ), and Zn(HL)2(Phen)2]·0.5H2O·1.5CH3OH ( 4 ) have been synthesized and structurally determined by X‐ray structure analyses. Among these complexes, the M(II) centers are all six‐coordinated in an octahedral coordination geometry, and HL? ligands bond to M(II) centers via nitrogen atoms in 1 and 2 , while via sulfur atoms in 3 and 4 , respectively. |
