The effect of water, ethylene glycol and polyethylene glycol as reaction medium on the structure and shape of Bi2S3 nanosized materials was investigated, and Bi2S3 nanoflowers and nanorods were characterized by SEM, TEM and XRD.展开更多

The crystal crystallizes in orthorhombic, space group Pnna, a=2.8189(5)nm, b=0.8407(2)nm, c=1.4554(2)nm, V= 3.4491(11)nm3 and Z=4. The complex is built up of infinite chains which are formed by trans Ni(en)2 μ (NC)2, cis μ (NC)2Ni(CN)2 and cis μ (CN)2Ni(en)2 groups. The variable temperature magnetic susceptibility has been measured in the 5～300K range. A magnetic susceptibility study indicates the presence of a weak antiferromagnetic interaction and gives it’s weiss constant θ=2.6K. CCDC: 207329.展开更多
