Abstract
Two piperazine-templated metal sulfate complexes, (C4N2H12)[Ni(H2O)6](SO4)2, I and (C4N2H12)[Co(H2O)6](SO4)2, II, have been synthesized by hydro/solvothermal reactions and their crystal structures analyzedby single crystal X-ray difraction methods. Complex I crystallizes in the monoclinic system, P21/n space group,a=12.920(3), b=10.616(2), c=13.303(2), β=114.09(1)o, Z=4, R1 II: monoclinic P21/n, a=12.906(3), b=10.711(2), c=13.330(2), β=114.10(2)o, Z=4, R1=0.032 for 4010 reflections. The crystal structuresof the piperazine-templated metal(II) sulfates demonstrate zero-dimensional compound constituted by diprotonatedpiperazine cations, metal(II) cations and sulfate anions. The structures of complex I and II are substantially4N2H12)[Cu(H2O)6](SO4)2. The central metal(II) atoms are coordinated by six water molecules in the octahedral geometry.The crystal structures are stabilized by three-dimensional networks of the Owater-H. Osulfate and Npip-H. Osulfatethe results of thermal analysis, the thermal decomposition reactions of the complex I was analyzed to havethree distinctive stages whereas the complex II proceed through several stages.
