Gmelin’s compound

BN species parallel those of CC. This parallelism does not hold so nicely for reactivity. The polarity and relative weakness of B—N bonds make BN species much more reactive than comparable CC species, at least with respect to polar additions or substitutions, and the reaction paths as well as the products may differ greatly. The chemistry of BN compounds with three- or four-coordinated B and N atoms is summarized in advanced textbooks, and the details can be found in Gmelin s handbook.

This pioneer research marked the start of vigorous development of the chemistry of organotin compounds containing Sn—N bonds862,973. Numerous publications appeared in reviews737,738,926,949,973,978,979 as well as in parts 18 and 19 of Gmelin s Handbook87. 

However, the rapid pace of rhodium chemistry has not been fully reflected in the review literature. The two extant English language reference works have been well overtaken by events.14,15 There is an invaluable compendium of the early work by Griffith,16 and a new edition of Gmelin s handbook has been published very recently.17 However, apart from these last two books and the ever increasing space devoted to the chemistry of the element in undergraduate texts there has been no systematic attempt to review the chemistry of this element apart from its organometallic compounds, which form the subject of the companion series.18... 

Chloropentaamminecobalt(III) chloride forms red-violet rhomb-shaped crystals which decompose on heating above 150° with the stepwise loss of ammonia. The solubility of the salt in water at 25° is 0.4 g./lOO ml. The compound readily aquates in hot water, forming the aquopentaammine chloride. Chloropentaamminecobalt(III) chloride reacts with hot aqueous ethylenediamine or dZ-propylenediamine to form tris (ethylenediamine) cobalt (III) chloride or the corresponding propylenediamine compound, with liberation of ammonia. Concentrated sulfuric acid at room temperature produces a complex hydrogen sulfate of the chloro-pentaamminecobalt(III) ion. Aqueous mercury(II) chloride forms a characteristic precipitate of a double salt, [Co(NH3)6Cl]Cl2-3HgCl2, suitable for microchemical identification. Complete physical and chemical data may be found in Gmelin s handbook. ... 

Note added in proof. This statement is no longer correct. The Gmelin-Institut has commenced publication of volumes in the 8th edition of Gmelin s Handbuch der anorganische Chemie specifically concerned with organometallic compounds. The first volume describes the derivatives of vanadium and chromium.

The whole held of boron chemistry is covered, in a most comprehensive manner, in the 28 volumes on boron of Gmelin s Handbook. Two summarize early results and coordination compounds are dealt with, in part or completely, in recent volumes. Useful chapters, relevant to the coordination chemistry of boron can be found in refs. 2-4. For general information, standard works are available while several others contain relevant chapters that will be referred to where appropriate. B NMR results are comprehensively surveyed in a recent book, ° with up to 300 pages of tabulated material, including all the known types of the boron coordination compounds, and serving as a useful guide. In 1964, only one review comprehensively covered the coordination chemistry of boron. Reviews relevant to specialized are of the field will be referred to under appropriate subheadings.

The parent compound is covered first, provided it is known or of importance. It is followed by the benzo-fused systems and finally by the partially or fully hydrogenated systems. Moreover, as in Gmelin s Handbuch der Anorganischen Chemie and Beilstein s Handbuch der Organischen Chemie, the principle of the latest possible classification is applied, that is, condensed systems of two or more heterocycles are discussed under the parent compound to be found last in the classification. Finally, in view of the fact that there are more than 70000 known heterocyclic systems, a selection had to be made. We have restricted ourselves to those systems... 

Gmelin is the oldest handbook of chemistry. As early as 1817 Leopold Gmelin published the Handbuch der theoretischen Chemie (Handbook of Theoretical Chemistry), which later on lead to the Handbuch der Anorganischen und Organometallischen Chemie (Handbook of Inorganic and Organometallic Chemistry). Nowadays, this handbook has more than 640 volumes. In December 1991 a part of Gmelin s Handbook was made available online in a database. It started with nearly 280,000 compounds. In 1997, when the database is expected to be complete, it will contain about 700,000 compounds. The database information is composed of the volumes published between 1924 and 1975, and, additionally, from ca. 110 technical journals, which were evaluated in order to cover the period from 1988 onward. The gap from 1975 to 1988 will be filled by 1997. Today 642,421 compounds are contained in the data-...
