英文摘要: A new tetradecaborate, [H3N(CH2)(2)NH3](2)[B14O20(OH)(6)] , was synthesized by a boric acid 'flux' method, and characterized by X-ray powder diffraction, ICP, IR, TGA and DTA analyses. Single-crystal X-ray diffraction analysis showed that it crystallized in the monoclinic space group P (1) over bar (No.2) with a=0.85092(10) nm, b=0.88678(11) nm, c=1.00724(13) nm, alpha=95.099(2), beta=96.950(2), gamma=6.845(2), V=0.66425(14) nm(3), Z=2, R-1=0.0625[I>2 sigma(I)], and wR(2)=0.1172(all data). The molecule structure of compound 1 comprises the isolated polyanion clusters [B14O20(OH)(6)](4-) and diprotonated ethylenediamine molecules. Each polyanion cluster contains an 8-ring enclosed by six B3O3 3-ring units. Adjacent clusters are further connected with each, other through strong hydrogen-bonding interactions of N(O)-H center dot center dot center dot O to form a three dimensional(3D) supramolecular structure with 2D pseudo channels along the [010] and [001] directions. The diprotonated ethylenediamine molecules located in the channels interact with the host through extensive hydrogen-bonds. Compound 1 presents few example containing isolated polyborate anions synthesized by a boric acid 'flux' method.
