Some binary phase compounds are molecular, e.g. carbon tetrachloride (CCl 4). More typically binary phase refers to extended solids. Famous examples zinc sulfide, which contains zinc and sulfur, and tungsten carbide, which contains tungsten and carbon. [1] Phases with higher degrees of complexity feature more elements, e.g. three elements in ...
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.

Three different crystallographic forms exist. Other binary silicon nitrogen compounds have been proposed (SiN, Si 2 N 3, Si 3 N) [86] and other SiN compounds have been investigated at cryogenic temperatures (SiN 2, Si(N 2) 2, SiNNSi). [87] Silicon tetraazide is an unstable compound that easily detonates. The phase diagram with phosphorus shows ...
In lithium aluminium hydride, the [AlH 4] − anion carries hydridic centers firmly attached to the Al(III). Although hydrides can be formed with almost all main-group elements, the number and combination of possible compounds varies widely; for example, more than 100 binary borane hydrides are known, but only one binary aluminium hydride.

Many binary compounds are known: with the exception of the nitrogen hydrides, oxides, and fluorides, these are typically called nitrides. Many stoichiometric phases are usually present for most elements (e.g. MnN, Mn 6 N 5, Mn 3 N 2, Mn 2 N, Mn 4 N, and Mn x N for 9.2 < x < 25.3).
The IUPAC definition of a solid solution is a "solid in which components are compatible and form a unique phase". [3]The definition "crystal containing a second constituent which fits into and is distributed in the lattice of the host crystal" given in refs., [4] [5] is not general and, thus, is not recommended.
For example, there is a weak bond between hydrogen and iodine in hydroiodic acid, making it a very strong acid. [ citation needed ] In the simplest case, binary acid names are formed by combining the prefix hydro- , the name of the non-hydrogen nonmetallic element, the suffix -ic , and adding acid as a second word.
