|
摘要: 在水热条件下,合成了1个新的双核锌配合物[(ZnCl2)(PyBIm)]2(PyBIm=2-(4-pyridyl)benzimidazole)。该配合物为单斜晶系,P21/n空间群,晶胞参数a=0.774 51(4) nm,b=1.252 49(5) nm,c=1.315 96(7) nm,β=100.294(3)°,V=1.256 0(1) nm3,Z=2。结构分析表明,Zn被2个Cl原子和来自PyBIm配体的2个N原子配位,形成了1个变形四面体结构。在该配合物中,Zn…Zn距离为 0.709 4(5) nm,结构中存在π…π堆积和氢键作用。 |

Abstract: A new binuclear zinc complex [(ZnCl2)(PyBIm)]2(PyBIm=2-(4-pyridyl)benzimidazole) has been synthesized by hydrothermal reaction. The complex crystallizes in triclinic P21/n space group with crystal cell parameters of a=0.774 51(4) nm, b=1.252 49(5) nm, c=1.315 96(7) nm, β=100.294(3)°, V=1.256 0(1) nm3 and Z=2. The crystal X-ray analysis shows that Zn atom is coordinated by two Cl atoms and two N atoms from two PyBIm ligands in a distorted tetrahedral geometry. The Zn…Zn separation is 0.709 4(5) nm, and the hydrogen bonding and π…π interactions also exist in the structure. CCDC: 800921. |
