英文摘要 | National Natural Science Foundation of China [40972035, 21233004, 21201144]; Technological Innovation Platform of Fujian Province [2006L2003]; Fundamental Research Funds for the Central Universities [2013121020]; Natural Science and Engineering Research Council of Canada; Canadian Foundation for Innovation; Alberta Innovation and Science; BC Advanced Education; Borates have exceptionally diverse fundamental building blocks (FBBs), but factors controlling the formation of borate FBBs are poorly understood. The title compound La[B5O8(OH)]NO3 center dot 2H(2)O crystallizes in the space group P2(1)/n with a=6.5396(12) angstrom, b=15.550(3) angstrom, c=10.6719(19) angstrom, beta=90A4(1)degrees and Z=4 at 173(2) K. Its structure has been refined from single-crystal X-ray diffraction data to R-1=0.049 (for 2465) and wR(2)=0.173 (for 2459 I > 2 sigma(I)). This structure analysis and first-principles calculations show that the change of the FBB from 3 Delta 2 square in the title compound to 2 Delta 3 square in La[B5O8(OH)(H2O)]NO3 center dot 2H(2)O is accompanied by a rotation of the NO3 group. FTIR, Rietveld and thermal analysis results show that the hygroscopic title compound is partially changed to La[B5O8(OH)(H2O)]NO3 center dot 2H(2)O, with the conversion of [BO3] to [BO3(H2O)] by water absorption.
