Ternary metal hydrides have the formula A x MH n, where A + is an alkali or alkaline earth metal cation, e.g. K + and Mg 2+. A celebrated example is K 2 ReH 9, a salt containing two K + ions and the ReH 9 2− anion. Other homoleptic metal hydrides include the anions in Mg 2 FeH 6 and Mg 2 NiH 4.
The chemistry of Mg is dominated by the +2 oxidation state and prior to 2007 only examples of crystalline compounds with short Mg-Mg distances that may indicate an Mg-Mg bond were known, such as the ternary metal hydrides Mg 2 RuH 4, Mg 3 RuH 3, and Mg 4 IrH 5 and magnesium diboride, [3] Calculations had also indicated the stability of the Mg 2 ...
Classical transition metal hydride feature a single bond between the hydrogen centre and the transition metal. Some transition metal hydrides are acidic, e.g., HCo(CO) 4 and H 2 Fe(CO) 4. The anions potassium nonahydridorhenate [ReH 9] 2− and [FeH 6] 4− are examples from the growing collection of known molecular homoleptic metal hydrides. [16]
In inorganic chemistry and materials chemistry, a ternary compound or ternary phase is a chemical compound containing three different elements. While some ternary compounds are molecular, e.g. chloroform ( HCCl 3 ), more typically ternary phases refer to extended solids.
Binary hydrogen compounds in group 1 are the ionic hydrides (also called saline hydrides) wherein hydrogen is bound electrostatically. Because hydrogen is located somewhat centrally in an electronegative sense, it is necessary for the counterion to be exceptionally electropositive for the hydride to possibly be accurately described as truly behaving ionic.
Wallace's research spanned many fields, including measurements of low temperature specific heat, investigation of magnetic and superconducting materials, and metal hydrides. The latter are useful as hydrogen storage materials. A commonality of much of this research was low temperature.
This naming method generally follows established IUPAC organic nomenclature. Hydrides of the main group elements (groups 13–17) are given -ane base names, e.g. borane, BH 3. Acceptable alternative names for some of the parent hydrides are water rather than oxidane and ammonia rather than azane.
Carbohydrides (or carbide hydrides) are solid compounds in one phase composed of a metal with carbon and hydrogen in the form of carbide and hydride ions. [ citation needed ] The term carbohydride can also refer to a hydrocarbon .
