Cu I NHC complexes feature the most common oxidation state by far, and the majority of such complexes are synthesized through method 1 or occasionally through method 4. [1] Of the over 650 Cu NHC complexes structurally characterized as of 2019, around half feature 2-coordinate Cu with a linear geometry, another quarter feature 3-coordinate Cu ...
In inorganic chemistry, Fajans' rules, formulated by Kazimierz Fajans in 1923, [1] [2] [3] are used to predict whether a chemical bond will be covalent or ionic, and depend on the charge on the cation and the relative sizes of the cation and anion. They can be summarized in the following table:
2 has the most ionic character, whereas the others, ZnCl 2, ZnBr 2, and ZnI 2, have relatively low melting points and are considered to have more covalent character. [2] The pnictogenides Zn 3 N 2 (notable for its high melting point [11]), Zn 3 P 2, Zn 3 As 2 and Zn 3 Sb 2, have various applications. [12] Other binary compounds of zinc include ...

The Roman numerals in fact show the oxidation number, but in simple ionic compounds (i.e., not metal complexes) this will always equal the ionic charge on the metal. For a simple overview see [1] Archived 2008-10-16 at the Wayback Machine , for more details see selected pages from IUPAC rules for naming inorganic compounds Archived 2016-03-03 ...
