摘要

A novel octanuclear heterometallic {Ni₆WNi}-substituted Keggin-type phosphotungstate [Ni(H₂O)(en)₂][WO₄]{[Ni₆(OH)₃(H₂O)₂(en)₃(Im)₂](B-α-PW₉O₃₄)}·2H₂O (1) with mixed organic ligands of en and Im (en = ethylenediamine, Im = Imidazole) has been hydrothermally synthesized and structurally characterized by IR spectra, powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA) and single-crystal X-ray diffraction. Notably, 1 is an interesting spoon-shaped monomeric polyoxometalate consisting of mixed organic ligands and unprecedented octanuclear heterometallic {Ni₆WNi} cores where the WO₄ tetrahedron is linked to the triangular {[Ni₆(OH)₃(H₂O)₂(en)₃(Im)₂](B-α-PW₉O₃₄)} clusters and [Ni(H₂O)(en)₂]^{2 +} cations through Ni-O_t-W linkages. Magnetic susceptibility measurements indicate ferromagnetic coupling within 1.
