通过乙醚缓慢地扩散到六水合苦味酸锰的DMF溶液中的方法得到了标题配合物[Mn2(Pic)4(DMF)8](Pic=苦味酸根阴离子)并进行了X-射线结构表征.该配合物晶体属单斜晶系,P2(1)/c空间群,晶体学参数为:a=15.2561(12),b=19.6756(16),c=12.1328(10)(A),β=94.4010(10)°,V=3631.2(5)(A)3,Z=2,C48H64Mn2N20O36,Mr=1607.07,Dc=1.470g/cm3,F(000)=1660,μ=0.451 mm-1,最终的一致性因子R=0.0424.在不对称单胞中存在着两种配位环境相同的Mn(Ⅱ)离子,四个DMF中的羰基氧原子和两个苦味酸根离子中的酚氧原子直接和Mn(Ⅱ)离子配位,形成了一个扭曲的八面体几何构型.

The title complex, [Mn2 (Pic)4 (DMF)8 ] (Pic = picrate anion), has been obtained by slow diffusion tal diffraction. It crystallizes in the monoclinic, space group P2( 1 )/c with a = 15. 2561 (12), b = 19. 6756(16), c = 12.1328(10)(A),β = 94.4010(10)°, V = 3631.2(5) (A)3, Z = 2, C48H64Mn2N20O36, Mr=1607.07, Dc= 1.470 g/cm3,F(000) = 1660,μ = 0.451 mm-1, R= 0.0424 andwR = 0. 1119 for4595observed reflections with I > 2σ(I). There are two kinds of Mn(Ⅱ) ions which have the same coordination environment in the asymmetric unit cell. The Mn(Ⅱ) is coordinated by four carbonyl O atoms from the DMF molecules and two phenolate O atoms of the picrate anions, forming a distorted octahedral structure.
