Abstract: The crystals of the title compound are orthorhombic with space group Pbca and a=23.3973(6)Å,b=22.5524(7)Å, c=15.1043(2)Å V=7970.02Å3, for Z=8.Diffracted intensities were collected on a Nicolet XRD R3 four-circle diffractometer using MoKα radiation.The scanning technique was employed with a scan range 3°<2θ<45°.All independent reflections were 5200 among which 2859 reflections were observable (Ⅰ>3σ(Ⅰ)).The structure was determined by the heavy atom method and refined by block-diagonal matric least-square method.The average Mn—N bond length is 2.005Å and Mn—Cl bond length is 2.370(3)Å.

Key words: Porphyrin complex, Crystal structure, X-ray diffractometry
