CRYSTAL-STRUCTURE AND MAGNETIC-PROPERTIES OF HETEROTRINUCLEAR COMPLEX, (CUTREN)(2)FE(CN)(6)CENTER-DOT-12H(2)O

A heterotrinuclear complex, (Cutren)(2)Fe(CN)(6).12J(2)O, was synthesi sed and its crystal structure solved by direct methods. Crystal data a re: C18H60N14Cu2FeO12, M = 847.7, monoclinic, space group: P2(1)/c, a = 13.568(5), b = 10.100(3), c = 13.935(6)Angstrom, beta = 95.50(4 degr ees, V= 1901(1) Angstrom(3), Z = 2, D-x = 1.48 gcm(-3) final R = 0.039 and R omega = 0.049. The crystal structure shows that the complex is composed of two (Cutren) and one hexacyanometallate Fe(CN)(6) subunits . Bridging cyano C(1)-N(1) is 1.148(4) Angstrom, which is shorter than non-bridging (1.155(4) Angstrom and 1.164(4) Angstrom). Magnetic prop erties of (Cutren)(2)Fe(CN)(6) indicate weak ferromagnetic exchange ov er the temperature range of 6.2-37K.
