Gmelin database

Last updated

The Gmelin database is a large database of organometallic and inorganic compounds updated quarterly. It is based on the German publication Gmelins Handbuch der anorganischen Chemie ("Gmelin's Handbook of Inorganic Chemistry") which was originally published by Leopold Gmelin in 1817; [1] the last print edition, the 8th, appeared in the 1990s. Although published over many decades, the printed series was not uniform in coverage or currency. Some elements are represented only by decades-old and not updated slim summary volumes. Others (Fe, B, S, F, U, etc.) have numerous supplements. Most later supplement volumes focused on an element's organic complexes. Each volume lists its literature coverage date. [2]

The database currently contains every compound/reaction discovered between 1772 and 1995, amounting to 1.5 million compounds and 1.3 million different reactions, with over 85,000 titles, keywords and abstracts. It has over 800 different data fields on subjects such as the compounds' electric, magnetic, thermal, crystal and physiological information.

The Gmelin database is maintained by Elsevier MDL. It is the sister database to the Beilstein database, which deals with organic chemicals and reactions; both are now part of the Reaxys system. The Gmelin database is less complete and less up-to-date than the handbook; the printed book is consequently kept available. [2]

Hydrogen bromide is the inorganic compound with the formula HBr. It is a hydrogen halide consisting of hydrogen and bromine. A colorless gas, it dissolves in water, forming hydrobromic acid, which is saturated at 68.85% HBr by weight at room temperature. Aqueous solutions that are 47.6% HBr by mass form a constant-boiling azeotrope mixture that boils at 124.3 °C (255.7 °F). Boiling less concentrated solutions releases H2O until the constant-boiling mixture composition is reached.

The Beilstein database is the largest database in the field of organic chemistry, in which compounds are uniquely identified by their Beilstein Registry Number. The database covers the scientific literature from 1771 to the present and contains experimentally validated information on millions of chemical reactions and substances from original scientific publications. The electronic database was created from Handbuch der Organischen Chemie, founded by Friedrich Konrad Beilstein in 1881, but has appeared online under a number of different names, including Crossfire Beilstein. Since 2009, the content has been maintained and distributed by Elsevier Information Systems in Frankfurt under the product name "Reaxys".

<span class="mw-page-title-main">Terbium(III,IV) oxide</span> Chemical compound

Terbium(III,IV) oxide, occasionally called tetraterbium heptaoxide, has the formula Tb4O7, though some texts refer to it as TbO1.75. There is some debate as to whether it is a discrete compound, or simply one phase in an interstitial oxide system. Tb4O7 is one of the main commercial terbium compounds, and the only such product containing at least some Tb(IV) (terbium in the +4 oxidation state), along with the more stable Tb(III). It is produced by heating the metal oxalate, and it is used in the preparation of other terbium compounds. Terbium forms three other major oxides: Tb2O3, TbO2, and Tb6O11.
