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.展开更多
The synthesis of nickel supramolecular compound with hexamethylenetetramine and fumarate ligands is reported.

The compound Ni(H2O)6(fum) ·2(hmt)·4H2O (1) (fum=fumarate; hmt=hexamethylenetetramine) were characterized by elemental analysis, crystal structure, IR. Compound 1 crystallizes in the triclinic system, space group P1, and with Z=1. Cell parameters: a=0. 934 6(1), b=0.933 8(1), c=0.938 8(2) nm, α=79.46(1)°, β=77.84(1)°, γ=61.29 6(7)°. Every metal ion has a octahedral coordination geometry formed by six oxygen atoms from six water molecules, and the relative independent components Ni(H2O)6 2+, fumarate anions, hmt and H2O molecules are linked together by two kinds of hydrogen bonds (O-H...O, and O-H...N) to form a three-dimensional structure.
