Crystal structure of mer-tris-(N-benzylsalicylaldiminato)manganese(III)

Abstract

The crystal structure of the title compound has been determined by the heavy-atom method from X-ray diffractometer data and refined by least-squares to R 0·05 (2991 reflections). Crystals are triclinic, space group p, a= 11·054(2), b= 16·462(3), c= 9·801(2)Å, α= 104·91(1), β= 93·20(2), γ= 94·02(2)°, Z= 2.

The three ligands are bidentate, co-ordinating through the oxygen and nitrogen atoms in the mer-conformation, i.e. trans-isomer. The manganese environment displays a pseudo-tetragonal distortion, the axial atoms being nitrogen [Mn–N 2·251(5) and 2·271(5)Å]. The equatorial atoms are at distances: Mn–O 1·882(3), 1·896(3), and 1·917(4), and Mn–N 2·082(5)Å.
