| 摘 要： | A novel hexa-NiⅡ substituted trilacunary Keggin polyoxometalate {Ni6（μ3- OH）3（en）3（H2O）6}（B-α-PW9O34）]-6H2O 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）A, γ = 120.000°, V = 7737.5（3）A3, Z = 6, GOF = 1.083, R （wR） = 0.0317 （0.0610）. Single-crystal X-ray diffraction indicates that 1 contains a hexa-Nin substituted trivacant Keggin {Ni6（μ3-OH）3（en）3（H2O）6}（B-α-PW9O34）] unit. The magnetic study shows the presence of ferromagnetic coupling interactions within hexa-Nin clusters with J1 = 0.69 cm-1 and J2 = 0.92 cm^-1 for 1.

| Abstract: | A novel hexa-NiⅡ substituted trilacunary Keggin polyoxometalate {Ni6(μ3-OH)3(en)3(H2O)6}(B-α-PW9O34)]·6H2O 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) A, γ = 120.000°, V = 7737.5(3) A3, Z = 6, GOF =1.083, R (wR) = 0.0317 (0.0610). Single-crystal X-ray diffraction indicates that 1 contains a hexa-NiⅡ substituted trivacant Keggin {Ni6(μ3-OH)3(en)3(H2O)6}(B-α-PW9O34)] unit. The magnetic study shows the presence of ferromagnetic coupling interactions within hexa-NiⅡ clusters with J1 = 0.69 cm-1 and J2 = 0.92 cm-1 for 1. |
