摘要：
Bromido-(3,3',4,4',8,8',9,9'-octaethyl-2,2'-bidipyrrinato)iron(III) crystallizes in two different polymorphs, space groups P1 and C2/c. with Z = 2 and 8, respectively, and slightly different densities. The Fe-N and Fe-Br bond lengths vary significantly with the polymorph indicating the presence of intermediate spin (S = 3/2) species admixed with different amounts of high spin (S = 5/2) iron(III) compounds in the triclinic resp. monoclinic form.
