Abstract

The title complex, (diethyl 3,4,8,15,19,20-hexamethyl-21,22,23,24-tetraazopentacyclo[16.2.1.1(2,5).1(7,11).1(14,17)]tetracosa-1(20),2(22),3,5,7,9,11,13(24),14,16,18-undecaene-9,14-dicarboxylate-kappa4N)iodoiron(III) chloroform solvate, [Fe(C32H32N4O4)I].CHCl3, shows an almost planar arrangement of the corrphycene moiety with a slightly distorted trapezoid pyramidal core; the Fe(III) atom is 0.416 (1) A from the plane of the C20N4 system. The Fe-N distances are 2.049 (3), 2.044 (3), 2.079 (3) and 2.075 (3) A. The solvated chloroform forms a C-H...O hydrogen bond [C...O 3.107 (10) A] to an adjacent carbonyl O atom. This is the first X-ray structure analysis of a corrphycenatoiron(III) derivative.
