Abstract
The title compound, ccc-[Ru(5mazpy)2Cl2] (5mazpy = 5-methyl-2-(phenylazo)pyridine) crystallized in monoclinic, space group P21/c with unit-cell parameters: a = 14.348(1)A, b = 12.705(1)A, c = 13.968(1)A, β = 111.18(1)°, Z = 4. According to the pairs of Cl, N(pyridine), and N(azo) coordinating with the Ru(II) ion, this complex has a cis-cis-cis (ccc) configuration. The Ru-N(azo) distances are relatively shorter than the Ru-N(pyridine) distances, due to strong π-backbonding of the azo moiety.
该化合物ccc-[Ru(5mazpy)2Cl2] (5mazpy = 5-甲基-2-(苯基偶氮)吡啶)在单斜空间群P21/c中结晶，晶胞参数为:a = 14.348(1) a, b = 12.705(1) a, c = 13.968(1) a， β = 111.18(1)°，Z = 4。根据与Ru(II)离子配位的Cl、N(吡啶)和N(偶氮)对，该配合物具有顺-顺-顺(ccc)构型。由于偶氮基团的强π背键作用，使得Ru-N(偶氮)的距离比Ru-N(吡啶)的距离短。
