氨基硫脲二羧酸锌化合物[Zn（tsc）_2（OH_2）_2][延胡索酸]_2、[Zn（tsc）_2]的合成和晶体结构（柠康酸）]·H2 O3，[Zn（tsc）（μ-1，4-苯二乙酸）] 4，[Zn（Ettsc）2 [Zn（Ettsc）2]·3H2O 5 [邻苯二甲酸][邻苯二甲酸]·H2O 6，[Zn（Metsc）2 [Zn（Me 2 tsc）2（OH 2）][对苯二甲酸锌]·2 H2O 8和[Zn（EtMe 2 tsc）2（OH 2）][对苯二甲酸锌] 9。对苯二甲酸酯和富马酸酯化合物2、8和9的超分子结构由阳离子和阴离子的链组成，其中离子通过氢键连接。相比之下，化合物3、5、6和7含有与金属中心配位的羧酸根基团，以得到中性或单阳离子物质。这些差异可以合理化的基础上的二羧酸盐结构，特别是之间的角度羧酸载体。化合物4以与硫脲衍生物类似的方式形成配位聚合物。
The syntheses and crystal structures of the zinc thiosemicarbazide dicarboxylate compounds [Zn(tsc)2(OH2)2][fumarate] 2, [Zn(tsc)2(citraconate)]·H2O 3, [Zn(tsc)(μ-1,4-phenylenediacetate)] 4, [Zn(Ettsc)2(citraconate)]·3H2O 5, [Zn(Ettsc)2(Hphthalate)][Hphthalate]·H2O 6, [Zn(Metsc)2(Hphthalate)][Hphthalate]·H2O 7, [Zn(Me2tsc)2(OH2)][terephthalate]·2H2O 8 and [Zn(EtMe2tsc)2(OH2)][terephthalate] 9 are reported. The supramolecular structures of the terephthalate and fumarate compounds 2, 8 and 9 consist of chains of cations and anions, in which the ions are linked by hydrogen bonding. In contrast, compounds 3, 5, 6 and 7 contain carboxylate groups co-ordinated to the metal centre to give either neutral or monocationic species. These differences can be rationalised on the basis of the dicarboxylate structure, in particular the angle between the carboxylate vectors. Compound 4 forms co-ordination polymers in an analogous manner to thiourea derivatives.
