摘要

Two new inorganic-organic hybrid germanotungstates built from trivacant Keggin fragments and in situ generated hexanickel clusters [Ni(en) ₂]_0.5[{Ni₆(μ₃-OH) ₃(en)₃(H₂O)₆}(B-α-GeW ₉O₃₄)]·₃H₂O (1) and [{Ni ₆(μ₃-OH)₃(dap)₃(H ₂O)₆}(B-α-GeW₉O₃₄)] ·H₃O·4H₂O (2) (en = ethylenediamine and dap = 1,2-diaminopropane) were hydrothermally synthesized and characterized by IR spectroscopy, elemental analysis, thermogravimetric analysis, single-crystal X-ray diffraction and magnetic analysis. Compound 1 crystallizes in the monoclinic space group P2₁/n; whereas compound 2 crystallizes in the monoclinic space group P2₁/c. Single-crystal X-ray diffraction indicates that both contain a hexa-Ni^II-substituted trivacant Keggin unit [{Ni₆(μ₃-OH)₃(L)₃(H ₂O)₆}(B-α-GeW₉O₃₄)] ^- (L = en or dap). Magnetic susceptibility measurements show the presence of ferromagnetic coupling interactions within the hexa-Ni^II clusters for 1 and 2.
