| 摘要: 本文作者采用2-羟基-4，6-二(2-吡啶基)-1,3,5-三嗪在室温下分别与氯化钠和氯化钙反应，得到了2种配合物[Na(OBPT)(H2O)]·2H2O (1)和[Ca(OBPT)(H2O)2Cl]·H2O (2)，并通过元素分析、红外、热重分析、粉末衍射和单晶衍射等方法对其结构进行了表征。单晶结构表明化合物1属于正交晶系的Pbca空间群，化合物2属于三斜晶系的P1 空间群。2个化合物都是一维链状结构，配体作为桥连配体采用三齿螯合和单齿配位的模式与2个金属配位。其中，化合物1中相邻2个配体的三嗪环几乎垂直，而化合物2中相邻2个配体的三嗪环则基本是共面的。 |

| Abstract: Two coordination compounds [Na(OBPT)(H2O)]·2H2O (1) and [Ca(OBPT)(H2O)2Cl]·H2O (2) were obtained at room temperature by reactions of 4,6-bis(2-pyridyl)-1,3,5-triazin-2-ol (HOBPT) with NaCl and CaCl2, respectively. They were characterized by elemental analysis, FTIR, powder X-ray diffraction analyses and single-crystal X-ray diffraction analyses. Single-crystal X-ray diffraction analyses indicate that complex 1 crystallizes in the orthorhombic Pbca space group, while complex 2 crystallizes in the triclinic P1. In complex 1, the sodium ion is coordinated with three nitrogen atoms from one ligand, a deprotonated hydroxyl oxygen atom from another ligand and a coordinated water molecule to form a one-dimensional structure. Similarly, compound 2 is also one-dimensional chain structure, however, the calcium ion is seven coordinated with one more coordinated water molecule and one chloride ion. Interestingly, the two triazine rings of the neighbouring ligands of 1 are almost vertical while those of 2 are coplanar. CCDC: 824484, 1; 824485, 2. |
