摘　　要：Compound [Ni(hmt)2(SCN)2(H2O)2][Ni(SCN)2(H2O)4](H2O)2 (hmt=hexamethylenetetramine) was prepared and structurally characterized by means of X ray single crystal diffraction. The two neutral units [Ni(hmt)2(SCN)2(H2O)2] and [Ni(SCN)2(H2O)4] are joined together through hydrogen bonds N…H-O, O…H-O and S…H-O. In the solid state, the compound has three dimensional network structure. The determination of its variable temperature magnetic susceptibilities (5～300K) shows that the magnetic behavior obeys the Curie Weiss law over the whole temperature ranges.Compound [Ni (hmt) (2) (SCN) (2) (H2O) (2)] [ Ni (SCN) (2) (H2O) (4)] (H2O) (2) (hmt = hexamethylenetetramine) was prepared and structurally characterized by means of X-ray single crystal diffraction. The two neutral units [ Ni (hmt) 2 (SCN) (2) (H2O) (2)] and [Ni (SCN) (2) (H2O) (4)] are joined together through hydrogen bonds (NH)-H-...-O, (OH)-H-... - O and (SH)-H-... - O. In the solid state, the compound has three-dimensional network structure. The determination of its variable-temperature magnetic susceptibilities (5 similar to 300K) shows that the magnetic behavior obeys the Curie-Weiss law over the whole temperature ranges.
