摘要: 将(1R,2R)-环己二胺与2-羟基-1-萘甲醛和3,5-二叔丁基水杨醛反应,得到非对称Salen配体H2L,然后将配体H2L与Ni(OAc)2·4H2O、Cu(OAc)2·H2O、Mn(OAc)2·4H2O进行配位反应,得到3个单核配合物[Ni(L)]·CH2Cl2(1),[Cu(L)](2),[Mn(L)(Cl)]·CH2Cl2(3),分别采用1H NMR、FT-IR和元素分析对化合物进行了表征,并通过X射线单晶衍射技术测定了配体和3个配合物的晶体结构。配体H2L属于正交晶系,P212121空间群。配合物1属于单斜晶系,P21/c空间群,而配合物2和配合物1的结构相似。配合物3属于三斜晶系,P1空间群。 |

Abstract: Reaction of (1R,2R)-diaminocyclohexane with 2-hydroxy-1-naphthaldehyde and 3,5-di-tert-butyl sali-cylaldehyde gave an asymmetric salen ligand H2L. Then H2L conducted the coordination reaction with Ni(OAc)2·4H2O, Cu(OAc)2·H2O and Mn(OAc)2·4H2O, and three mononuclear complex of[Ni(L)]·CH2Cl2 (1),[Cu(L)] (2) and[Mn(L)(Cl)]·CH2Cl2 (3) were obtained. The compounds were characterized by 1H NMR, FT-IR and elemental analysis respectively and the crystal structure of ligand and three complexes were measured through X-ray single crystal diffraction technology. The ligand H2L belongs to the orthorhombic system, P212121 space group. Complex 1 belongs to the monoclinic system, P21/c space group, and the structures of complex 2 and 1 are similar. Complex 3 belongs to the triclinic system, P1 space group. |
