N2 - Four new hexa-nickel(II)-substituted Keggin-type tungstophosphates [Ni6(μ3-OH)3(oeen)3(H2O)3(B-α-PW9O34)]·6H2O (1, oeen = N-(2-hydroxyethyl)enediamine), [Ni6(μ3-OH)3(oeen)3(H2O)4(B-α-PW9O34)]2·13H2O (2), [Ni6(μ3-OH)3(oeen)2(tran)(H2O)3(B-α-PW9O34)]·3H2O (3, tran = 1,4,7-triazonane) and [Ni6(μ3-OH)3(oeen)2(tran)(H2O)2(B-α-PW9O34)]·6H2O (4) have hydrothermally made by controlling their reaction temperatures. 1-4 have been characterized by elemental analyses, IR spectra, powder X-ray diffraction, thermogravimetric analyses and single-crystal X-ray diffraction, respectively. Structural analyses reveal that they consist of {Ni6(μ3-OH)3(H2O)n}9+ cores and B-α-PW9O34 (PW9) units, and further are stabilized by organic neutral oeen/tran molecules. 1-3 are isolated clusters while 4 is the 1D chain structure. It should be noted that the tran molecules in 3 and 4 are derived from the oeen molecules in the starting materials.
