STRUCTURE OF MONOMERIC HYDRATED MANGANESE(III) TETRA(4-N-METHYLPYRIDYL)-PORPHYRIN PENTACHLORIDE

The structure of the title compound, diaqua{2,7,12,17-tetrakis (1-methyl-4-pyridyl)-21,22,23,24-tetraazapentacyclo[16.2.1.1(3,6)1.1(8,11).1(13,16)]tetracosa -1(21),2,4,6(22),7,9,11(23),12,14,16(24),17,19-dodecaene-N21,N22,N23,N24}manganese(III) pentachloride heptahydrate, Mn-tmpyp, is the second example of a planar diaqua-ligated metalloporphyrin with an extensive anion-water network which interdigitates between successive layers of porphyrins. The Mn atoms have near octahedral geometry: Mn-N1 2.012(5), Mn-N2 2.013 (5), Mn-O1 2.221 (5) angstrom, N1-Mn-O1 90.2 (2), N2-Mn-O1 89.1 (2)degrees. The pyridyl planes are inclined by 65.0-degrees (C11-C12-C13-N12-C14-C15) and 71.2-degrees (C16-C17-C18-N11-C19-C20) with respect to the least-squares plane through the porphyrin.
