Synthesis and Structural Characterization of 2-PyrazinecarboxylateZinc Compound {[Zn2(Pyz)2(H2O)4] · SO4}_n(Pyz = 2-Pyrazinic Acid)

摘要

A solvothermal reaction of 2-pyrazinic acid with Zn(SO4)2 · 7H2O yielded the title complex of the formula {[Zn2(Pyz)2(H2O)4] · S04}_n (I). X-ray diffraction study shows that the complex I crystallizes in mono-clinic system, space group P21/c, with lattice parameters a = 11.2687(6), b = 7.3511(4), c = 11.8506(7) A, β = 95.070(2)°, V= 977.83(9) A~3, Z= 4, and ρ_(calcd) = 2.184 mg m~(-3).
