两个基于多金属氧酸盐和水杨醛缩氨基硫脲的有机-无机杂化配合物的合成与晶体结构

Synthesis and crystal structure of two polyoxometalate-based organicinorganic hyrid complexes with salicylaldehyde thiosemicarbazone

采用自然蒸发法,合成了2个新颖的有机-无机杂化配合物[C_8H_6N_3S]_2[H_2Mo_2O_7](1)和[CoⅡ(C_8H_8N_3OS)_2]_2[H_3PW_(12)O_(40)]·4DMF(2),并对其进行了元素分析、IR、TG和单晶X-射线衍射表征.结果表明:化合物1是由1个双核多阴离子[H2Mo2O7]2-与2个有机组分[C_8H_6N_3S]+通过共价键形成的一维链状结构;化合物2是由水杨醛缩氨基合钴与DMF分子及多酸阴离子通过氢键作用形成的三维网状结构,其中水杨醛缩氨基硫脲合钴呈风车型.

Two novel organic-inorganic hyrid complexes[C_8H_6N_3S]_2[H_2Mo_2O_7]（1） and [Co~Ⅱ（C_8H_8N_3OS）_2]_2 [PW_（12）O_（40）]·4DMF（2） were synthesized and characterized by elemental analyses, IR, TG and single crystal X-ray diffraction. Compound 1 consists of one [H_2Mo_2O_7]^（2-） dual-core anion and two [C_8H_6N_3S]＋ cations and forms a 1D chain structure by covalent bond. Compound 2 consists of Co-salicylaldehyde amino cobalt,DMF molecules and polyoxoanions and forms a 3D network by hydrogen bond. Co-salicylaldehyde amino cobalt was wind model.
