New trimethylhydrometallatranes, tris(2-hydroxypropyl)amine complexes with NiII, ZnII, CuII, and CoII salts of biologically active carboxylic acids (benzoic, cinnamic, salicylic, succinic), were synthesized. The structure of the tris(2-hydroxypropyl)amine complex with nickel(II) cinnamate was determined by single-crystal X-ray diff raction. Thermal stability of the synthesized tris(2-hydroxypropyl)amine complexes was compared with that of tris(2-hydroxyethyl)- amine complexes.

三（2-羟丙基）胺与生物活性羧酸的 NiII、ZnII、CuII 和 CoII 盐的合成和结构

合成了新的三甲基氢金属特拉烷、三（2-羟丙基）胺配合物与 NiII、ZnII、CuII 和 CoII 盐的生物活性羧酸（苯甲酸、肉桂酸、水杨酸、琥珀酸）。三（2-羟丙基）胺与肉桂酸镍（II）络合物的结构由单晶X射线衍射确定。合成的三(2-羟丙基)胺配合物的热稳定性与三(2-羟乙基)-胺配合物的热稳定性进行了比较。
