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.
Rubidium silver iodide is a ternary inorganic compound with the formula RbAg 4 I 5.Its conductivity involves the movement of silver ions within the crystal lattice. It was discovered by Dr. Boone Owens while searching for chemicals which had the ionic conductivity properties of alpha-phase silver iodide at temperatures below 146 °C for AgI.
The compound In 2 Te 5 is a polytelluride containing the Te 2− 3 unit. None of the indium chalcogenides can be described simply as ionic in nature, they all involve a degree of covalent bonding. However, in spite of this it is useful to formulate the compounds in ionic terms to get an insight into how the structures are built up.
Silver acetate is a coordination compound with the empirical formula CH 3 CO 2 Ag (or AgC 2 H 3 O 2). A photosensitive , white, crystalline solid, it is a useful reagent in the laboratory as a source of silver ions lacking an oxidizing anion.
The circumstances under which a compound will have ionic or covalent character can typically be understood using Fajans' rules, which use only charges and the sizes of each ion. According to these rules, compounds with the most ionic character will have large positive ions with a low charge, bonded to a small negative ion with a high charge. [25]
In chemistry, an ionic crystal is a crystalline form of an ionic compound. They are solids consisting of ions bound together by their electrostatic attraction into a regular lattice . Examples of such crystals are the alkali halides , including potassium fluoride (KF), potassium chloride (KCl), potassium bromide (KBr), potassium iodide (KI ...
A stannide can refer to an intermetallic compound containing tin combined with one or more other metals; an anion consisting solely of tin atoms or a compound containing such an anion, or, in the field of organometallic chemistry an ionic compound containing an organotin anion (e.g.see [1] an alternative name for such a compound is stannanide.)
Compounds of nickel with other metals can be called alloys. The substances with fixed composition include nickel aluminide (NiAl) melting at 1638° with hexagonal structure. [4] NiY, NiY 3, Ni 3 Y, Ni 4 Y, NiGd 3, [16] BaNi 2 Ge 2 changes structure from orthorhombic to tetragonal around 480 °C. [17] This is a ternary intermetallic compound.
