A new neodymiumIII-ironIII complex [Nd(DMSO)5(H2O)2](μ-CN)[Fe(CN)5] (DMSO = dimethyl sulfoxide) has been synthesized by the grinding reaction method. The crystal belongs to monoclinic, space group P21/m with a = 8.859(4), b = 13.684(5), c = 12.290(4) ?, ?= 91.85(2)o, C16H34FeN6NdO7S5, Mr= 782.88, V = 1489(1) ?3, Z = 2, Dc = 1.746 g/cm3, S = 0.906, μ(MoKa) = 2.606 mm-1, F(000) = 788, R = 0.0646 and wR = 0.1654. The slightly distorted square-antiprism eightfold-coordinated Nd(III) and approximately oriented octahedrally sixfold- coordinated Fe(III) are linked by a cyano-bridge group to construct a dinuclear compound. The [Nd(DMSO)5(H2O)2](μ-CN)[Fe(CN)5] species are held together via hydrogen bonds to form a three-dimensional framework.

“小先生”,顾名思义就是让学生做“教师”,通过“兵教兵”大面积提高学习质量。而这一最佳途径则需要通过小组合作来实现。因此,笔者认为,要尽可能在小组合作中,通过“兵教兵”的模式解决一些基本问题。换句话说,也就是教师要善于在课堂上培养“小先生”,使其成为自主课堂上一道亮丽的风景。  一、鼓励争当“小先生”,挖掘学习资源  三人行,必有我师焉。陶行知也说过,人人都可以当“小先生”。关键是学生要有自信心,
