Abstract
The tetracupferronato-bis(mu-methoxy)-diiron(III) complex has been syn thesized in acetonitrile and its crystal structure determined C26H26N8 O10Fe2, monoclinic, space group C2/c, a = 18.425(3), b = 12.999(2), c = 15.046(3) Angstrom, beta = 124.66(2)degrees, V = 2964(1) Angstrom(3) , Z = 4, wR(2) = 0.097 from 1491 reflections (F-2). Two iron(III) atom s are at special positions in six-fold coordination, bridged by O with a Fe-O-Fe angle of 102.4(1)degrees and a distance between two iron(II I) centers of 3.075(1) Angstrom. Temperature-dependent magnetic suscep tibility measurements reveal a antiferromagnetic exchange interaction (J = -14 cm(-1)) between the iron(III) centers.
