A new coordination compound,Ni(C6H12N4)2SO4·4H2O(NSH-HMTA)(HMTA,hexamethylenetetramine,C6H12N4),has been synthesized and its single crystals were obtained.NSH-HMTA belongs to the triclinic system,space group P1 with a=9.2534(6),b=13.3131(2),c=16.0373(2) ?,α=65.981(6),β=89.792(3),γ=89.677(4)°,Mr=880.2,Z=2,V=1804.6(3) ?3,μ=1.254 mm-1,F(000)=932,R=0.0555(I > 2σ(I)) and w R=0.1908 for 19343 observed reflections.HMTA substitutes for water molecules are located at the para-positions,forming a stretching octahedral nickel ion unit.Thermo-gravimetric analysis shows that the dehydration temperature of NSH-HMTA is about 92 ℃.The characteristic UV peaks are approximately 10 nm red-shifted by the absorption of octahedral HMTA complex ion units.
