摘要
从A μ -酚- μ -氯-桥接双核锰(II)与2,6-双(N -(4-咪唑乙基)亚甲基)-4-甲基苯酚(Hbimmp)配合物中分离得到[Mn 2 (bimmp)(μ -Cl)Cl 2]。在293 K下用单晶x射线衍射法测定了晶体结构。配合物在正交空间群F dd2中结晶，a = 40.557(4)， b = 9.2353(9)， c = 12.5138(2)Å， V = 4687.1(8)Å 3, D calcd = 1.603 g/cm 3, Z = 8。所有2683个独立反射的R 1 [I > 2 σ (I)]和wR 2(所有数据)值分别为0.0309和0.0826。两个锰(II)原子由一个苯基氧原子和一个μ -氯原子桥接，其中每个锰(II)原子进一步由苯基氧原子和氯原子的亚氮原子和咪唑氮原子配位，形成方形金字塔几何结构。(收到
μ-Phenolato-μ-chlorido-bridged Dinuclear Manganese(II) Complex with a Dinucleating Schiff-base Ligand Having Imidazolyl Groups
in A μ -phenolato- μ -chlorido-bridged dinuclear manganese(II) complex with 2,6-bis( N -(4-imidazolylethyl)iminomethyl)-4-methylphenol (Hbimmp), [Mn 2 (bimmp)( μ -Cl)Cl 2 ], was isolated. The crystal structure was determined by a single-crystal X-ray diffraction method at 293 K. The complex crystallizes in the orthorhombic space group F dd2 with a = 40.557(4), b = 9.2353(9), c = 12.5138(2)Å, V = 4687.1(8)Å 3 , D calcd = 1.603 g/cm 3 , Z = 8. The R 1 [ I > 2 σ ( I )] and wR 2 (all data) values are 0.0309 and 0.0826, respectively, for all 2683 independent reflections. The two manganese(II) atoms are bridged by a phenolato-oxygen of bimmp – and a μ -chlorido atom, where each manganese(II) atom is further coordinated by imino- and imidazolyl-nitrogen atoms of bimmp – and chlorido atoms to form a square-pyramidal geometry.
