Abstract

A novel hexa-Ni^II subbstituted trilacunary Keggin polyoxometalate Ni₆ μ₃-OH ₃(en)₃ H₂O ₆ B-α-PW₉O₃₄-6H ₂O 1 (en = ethylenediamine) has been hydrothermally synthesized and characterized by IR spectra, elemental analysis, thermogravimetric analysis (TGA), single-crystal X-ray diffraction and magnetic property. Compound 1 crystallizes in the hexagonal space R3c with a = 20.4124(5), c = 21.4427(4) Å, γ = 120.000°, V = 7737.5(3) Å³, Z = 6, GOF = 1.083, R(wR) = 0.0317 (0.0610). Single-crystal X-ray diffraction indicates that 1 contains a hexa-Ni^II substituted trivacant Keggin Ni ₆(μ₃-OH)₃(en)₃(H ₂O)₆}(B-α-PW₉O₃₄ unit. The magnetic study shows the presence of ferromagnetic coupling interactions within hexa-Ni^II clusters with J₁ = 0.69 cm^-1 and J₂ = 0.92 cm^-1 for 1.
