SYNTHESIS, CHARACTERIZATION AND STRUC-TURE OF BIS(1,8-NAPHTHYRIDINE-N-OXIDE) STRONTIUM NITRATE CON-TAINING DOUBLE BIDENTATE AND BRIDGING NITRATE GROUP

A new complex formed from strontium nitrate and 1,8-naphthyridine-N-oxide with a 1:2 stoichiometry has been synthesized and characterized by elemental analyses, infrared spectra, Raman spectra, fluorescence spectra, DTA-TG, solubility and molar conductance measurements. A single crystal X-ray structural analysis indicates that a kind of double bidentate and bridging nitrate group which has never been reported in literature is present in the new complex. The coordination number of the strontium ion is 10.     

存在双二齿桥联硝酸根的二(氧化1,8-萘啶)合硝酸锶的合成、性质及结构

本文合成了硝酸锶与氧化1,8-萘啶组成为1:2的固体配合物。对配合物进行了元素分析、红外光谱、拉曼(Raman)光谱、荧光光谱、差热-热重谱图,溶解性及摩尔电导等测定。X射线单晶衍射结构分析表明,在配合物中存在一种文献中未曾报道过的双二齿桥联硝酸根。锶的配位数为10。
