Two novel mixed valence copper coordination polymers, [Cu(2-pac)2(CuN3)(H2O)]n (1) and [Cu(2-pac)2(CuSCN)2]n (2), have been prepared through hydrothermal synthesis and analyzed for structure determination, which exhibit two and three-dimensional structures respectively. In complex (1), zigzag chains of [CuN3]n running parallel to the c direction are interconnected by Cu(2pac)2 to form a two-dimensional layer structure. In complex (2), the arrangement ofμ-1,1,3 bridging thiocyanate ligand leads to the formation of ten-membered Cu-SCN-Cu-S-Cu-NCS rings, and each Cu atom is further linked by Cu(2-pac)2 to afford a three-dimensional configuration.

摘 要随着互联网技术的不断发展,互联网在教学中的运用越来越广泛,同时也推动了教学模式的改革。在我国现有的教学模式中往往采取灌输式教学方法,使学生学习兴趣骤降,不利于激发学生学习主动性。而在教学中使用翻转课堂教学方法,可以为教学提供新途径,激发学生学习兴趣。  【关键词】翻转课堂;教学;教师  翻转课堂主要以信息技术为支撑,通过录制微视频的方式,颠覆传统教学模式。翻转课堂主要是以学生为中心开展教学的
