| 摘要: 通过水热法合成了一个新的金属-有机配位聚合物[Mn(C2O4)(bimb)]n·0.25nH2O(H2C2O4=草酸,bimb=1,4-双(咪唑基-1-基)丁烷)。并对其进行了元素分析、红外光谱、紫外光谱、热重和X-射线单晶衍射测定。该配合物属于三斜晶系,P1空间群。在晶体结构中,锰原子为六配位与来自2个不同的C2O42-配体上的4个羧基氧原子和来自2个bimb配体上的2个氮原子配位,呈现畸变的八面体几何构型。 |

| Abstract: A new metal-organic coordination polymer [Mn(C2O4)(bimb)]n·0.25nH2O (1) (H2C2O4=oxalic acid, bimb=1,4-bis(imidazol-1-yl)-butane) has been hydrothermally synthesized and structurally characterized by elemental analysis, IR, UV spectrum, TG and single-crystal X-ray diffraction. The title compound crystallizes in the triclinic system, space group P1 with a=0.928 62(12) nm, b=0.965 61(13) nm, c=0.972 27(13) nm, α=67.992(2)°, β=87.361(2)°, γ=64.596(2)°, V=0.723 25(17) nm3, C24H29Mn2N8O8.5, Mr=675.43, Dc=1.551 g·cm-3, μ(Mo Kα)=0.936 mm-1, F(000)=347, Z=1, R=0.031 2, wR=0.074 9. In the crystalstructure, the manganese atom is six-coordinated with four carboxylate oxygen atoms from two different C2O42- ligands and two nitrogen atoms from two bimb ligands, showing a distorted octahedral geometry. CCDC: 929937. |
