摘要
Compound Mn(N 3) 2(4, 4’ bipy) n having three dimensional structure was obtained with crystallographic data: C 10 H 8N 8Mn ( M r =295.16), tetragonal, space group P4 12 12 1(#99), a=8.220(2), c=16.918(5) , V=1143.1(5) 3, Z=4, D c =1.715 g/cm -3 , μ =11.07 cm -1 , F(000)=596, R=0.042, R w =0.051, for 590 observable reflections. The special topology structure in the compound occurs from the helical chain consisting of the -Mn-N-N-N-Mn’ unit. The value of χ mT decreases with the decreasing of temperature
