摘　　要：报道了标题化合物([Mn(Ⅲ)OH·H_2O·TMAP]·I_3·Cl·9H_2O)的合成和晶体结构。晶体属P2_(1/a)空间群,a=1.8502(1)nm,b=1.2738(1)nm,c=3.0458(2)nm,β=104.52(4)°,Z=4,R=0.096,R_w=0.087.用顺磁和光谱电化学证明卟啉配合物中心锰为三价,确定了锰卟啉轴向两个配位氧原子,一个属水分子,另一个属氢氧根。讨论了锰卟啉的稳定氧化态。The title compound([Mn( Ⅲ )OH·H2O-TMAP]·I3·Cl·9H2O) was synthesized and characterized by X-ray diffraction method. The crystal belongs to monoclinic system, space group P21/a with a= 1.8502(1) nrn, 6=1.2138(1) nm, c=3.0459(2) nm, β=104.52(4)°, Z = 4, V=6. 9513 nm3, Dc = 1. 492 g·cm-3, R = 0. 096, Rw = 0. 087.The two oxygen atoms coordinated to manganese( Ⅲ ) were determined by recognizing central manganese valence with ESR and Spectroelectrochemistry. The stable manganese valence of the coordination was discussed.
