Synthesis, crystal structure and ferromagnetic properties of a new dicyanamide bridged dicopper(Ⅱ) complez with IM-1”-MeBzIm -k2 N, O mode

摘要：

The crystal structure of ”Cu2(NO3)2(IM-1”-MeBzIm)2(dca)2”(IM-1”-MeBzIm=2-”2”-”(1”-methyl)benzimidazolyl””-4,4,5,5-tetramethylimidazoline-1-oxyl, dca=dicyanamide anion) triclinic, space group P-1, Z=1. Crystal data: C34H40Cu2N16O8, Mr=927.90, a=9.440(5), b=10.124(6)), c=11.603(7) (A), β=94.033(6)° V=1038.2(10) (A)3, Dc=1.484 g/cm3, μ(MoKα)=1.093 mm-1, F(000)=478, R=0.0609 and wR=0.1512 for 2456 observed reflections with Ⅰ＞2σ(Ⅰ). The magnetic properties for the title complex has been investigated in the temperature range 2 ～300 K and there are ferromagnetic interactions between the coordinated nitronyl nitroxides(J=12.46 cm-1) and intramolecular ferromagnetic interactions.
