초록

벤젠 존재 하에서, DMF와 에탄올의 혼합 용매에서 zinc(II) nitrate $(Zn(NO_3)_2\;{\cdot}\;6H_2O)$와 $ATP(2-aminoterephthalate,\;H_2N-C_6H_3-1,4-(COO)_2)$의 용매열 반응으로 2차원 배위 고분자 [Zn(ATP) (DMF)] (1)이 얻어졌다 X-ray구조 결정 결과, 2개의 아연 금속과 4개의 ATP 리간드가 paddle-wheel유형의 2차 쌓음 단위들을 형성하고, 이것들은 ATP 리간드에 의해서 연결되어 2차원 4각 망을 이룬다는 것이 밝혀졌다. 아연 금속을 기준으로 각 4각형의 크기는 약$11.1\times11.1\;{\AA}$효이다. 고분자 1을 양질의 결정 상태로 얻기 위해서는 벤젠이 요구되었다.

The solvothermal reaction of zinc(H) nitrate $(Zn(NO_3)_2\;{\cdot}\;6H_2O)$ with $ATP(2-aminoterephthalate,\;H_2N-C_6H_3-1,4-(COO)_2)$ in a mixture of solvents of DMF and ethanol, in the presence of benzene, gave a 2 dimensional zinc polymer [Zn(ATP) (DMF)] (1). X-ray structure determination revealed that two zinc metals and four ATP ligands form the paddle-wheel SBUs, which are linked by the ATP ligands to give a 2-D square-grid network. Each square grid has approximate dimensions of $11.1\times11.1\;{\AA}$ based on Zn metals. Benzene was required to produce high-quality crystals of polymer 1.
