课程名称：配位化合物 课程概述：本课程以阿尔萨斯的工人之子——维尔纳为中心，他在年轻时便对化学产生了浓厚兴趣。在18岁时，他独立进行科研实验。在南德军队服役期间，他听取了一系列化学讲座，随后在瑞士苏黎世大学获得博士学位，并在29岁时被任命为化学教授。维尔纳因其在配位化合物方面的贡献，于1913年获得诺贝尔化学奖，这些研究是在他研究生阶段进行的，并在26岁时首次展示。维尔纳对配位化合物结构之谜的执着，甚至让他的思维在睡眠中也继续运作。1891年，时年仅25岁的他在半夜醒来，仅用几个小时便奠定了现代配位化学的基础。 课程还会介绍双盐的概念，双盐是由两种或多种稳定化合物在化学计量比下结合形成的分子化合物，尽管它们只存在于晶体结构中，但在溶于水或其他溶剂时会分解为各自的成分，且其物理和化学性质基本上仍与单一化合物相同。与此不同，配位化合物也是由多个稳定化合物以化学计量比结合而成，然而它们在溶解于水或其他溶剂后仍保持其身份，且其性质与组成成分完全不同。 课程大纲：无
Werner, the son of a factory worker, was born in Alsace. He developed aninterest in chemistry at an early age, and he did his first independent research experiments at age 18. While doing his military service in southern Germany, he attended a series of chemistry lectures, and he subsequently received his PhD at the University of Zurich in Switzerland, where he was appointed professor of chemistry at age 29. He won the Nobel Prize in Chemistry in 1913 for his work on coordination compounds, which he performed as a graduate student and first presented at age 26. Apparently, Werner was so obsessed with solving the riddle of the structure of coordination compounds that his brain continued to work on the problem even while he was asleep. In 1891, when he was only 25, he woke up in the middle of the night and, in only a few hours, had laid the foundation for modern coordination chemistry.Double salts are molecular compounds formed by the combination of two or more stable compounds in stoichiometric ratio. They exist only in crystal lattices but break down into their constituent compounds when dissolved in water or any other solvent. Their physical and chemical properties remain essentially the same as those of the individual compounds.Coordination compounds are also formed by the combination of two or more stable compounds in stoichiometric ratio. They retain their identities even when dissolved in water or any other solvent and their properties are completely different from those of the constituents.
