在HCl和水存在下，通过tib与CuBr的一锅法合成，得到了两种具有相同1,3,5-三(1-咪唑基)苯(tib)配体{[Cu(tib)2]·(H2O)2·Br2}n(1)和{[Cu2(tib)·Br·Cl]·2Br}n(2)的新的不同Cu(II) MOFs。 X射线单晶衍射分析表明配合物1和2均具有包含不同结构单元的二维骨架。配合物 1 中的每个 Cu(II) 原子均由来自不同 tib 配体的四个 N 原子配位。然而，complex2中有两个不同的密码Cu(II)原子，一个是由来自不同tib配体的两个溴原子和两个N原子配位的四个原子，另一个是由来自不同tib配体的两个氯原子和四个N原子配位的六个原子。文中描述了配合物1和2的热重分析。
Two new different Cu(II) MOFs with the same 1,3,5-tris(1-imidazolyl) benzene (tib) ligand {[Cu(tib)2]·(H2O)2·Br2}n(1) and {[Cu2(tib)·Br·Cl]·2Br}n(2) were obtained by one pot synthesized of tib with CuBr in the presences of HCl and water. X-ray single crystal diffraction analyses indicate that both complexes1and2have two dimensional frameworks containing different building blocks. Each Cu(II) atom in complex1is coordinated by four N atoms from different tib ligands. However, there are two different cryptographic Cu(II) atoms in complex2, one is four coordinated by two bromine atoms and two N atoms from different tib ligands, the other is six coordinated by two chloride atoms and four N atoms from different tib ligands. The thermal gravimetric analysis of complexes1and2are depicted in the paper.
