Abstract
The title compound has been prepared and its spectroscopic and magnetic properties and X-ray structure have been studied. The structure was solved from diffractometer data by Patterson and Fourier methods and refined by least-squares techniques to R 4·1 % for 914 independent reflections. Crystals are monoclinic, space group P21/c, with unit-cell dimensions: a= 12·096(6), b= 9·084(5), c= 15·447(7)Á. β= 106·8(1)°, Z= 4. The structure consists of dimers in which two atoms of manganese(III) are joined by two methoxo-groups (Mn–O 1·901, 2·227 Å). The co-ordination is tetragonally elongated (distorted) octahedral. The ligand salicylaldehyde anthraniloylhydrazone acts as a bridge between adjacent dimers and co-ordinates to one Mn through three atoms (Mn–O 1·895 and 1·912, Mn–N 1·967 Á) and to another through one atom (Mn–N 2·534 Å), so the whole structure is polymeric.Keywords
