Neuere Anschauungen auf dem Gebiete der anorganischen Chemie


IN 1893 Prof. Werner published his first important paper on the constitution of inorganic compounds, and expounded a new theory for the classification of the large and complex group of substances known as metal-ammonia compounds. Of these compounds a few are common enough, such as the deep blue substance formed by the addition of ammonia to solutions of copper salts, but the greater number do not come within the range of ordinary analytical chemistry; they are for the most part of no industrial importance, and consequently they are scarcely heeded except by a very limited number of chemical workers. The class of cobaltamines which has vexed many a generation of chemical students does not measure the limits of complexity to which these compounds extend, and certainly, without the guiding light of some good theory as to their structure, the metal-ammonia group constitutes one of the most bewildering tracts of inorganic chemistry.
