A new Cu(Ⅰ) coordination polymer,[Cu4(MA)2(HCA)2]n (1,MA =melamine,H3CA =cyanuric acid),has been synthesized under hydrothermal conditions using CuC12·2H2O and MA as the starting materials.Interestingly,cyanuric acid was obtained by the in situ hydrolysis and the deaminization of melamine,and the Cu(Ⅰ) ion was obtained by the in situ reduction of Cu(Ⅱ) ion during the self-assembly process.The crystal structure is of monoclinic,space group Pc with a =3.539(3),b =22.377(2),c =15.844(1) (A),β =90.723(1)°,V =1254.6(2) (A)3,C12H14Cu4N18O6,Mr =760.61,Z =2,Dc =2.013 g/cm3,F(000) =752,μ =3.426 mm-1,R =0.0479 and wR =0.1243 for 3172 observed reflections (I ＞ 2σ(I)).The crystal structural analysis revealed that the cooperation of coordinate-covalent bonds,intermolecular hydrogen bonds and π-π interactions give rise to a 3D supramolecular framework with 5-connected BN topology.Moreover,the thermal stability and luminescent property of 1 were also investigated.

简介:徐荣华,江苏省江浦职业教育中心校校党总支书记中学高级教师。 摘要:进入二十一世纪以后,全省的中等职业教育得到了飞速发展,学校的规模和办学条件都有了很大改善;然而如何评估一所学校的优劣、如何加大职业学校教师的发展动力、如何加大职业学生的学习压力,这三大问题一直制约着职业教育健康快速的发展。构建全省学生培养质量监控体系,无疑是解决以上三个问题,从而从根本上提高学校人才培养的质量的最佳途径。
