11.1.2.Names of complexes of various types l.The basic procedure for naming a complex(英语命名 法)： 1When naming a complex ion,the ligands are named before the metal ion. 2Write the names of the ligands in alphabetical order. i)multiple occurring monodentate ligands receive a prefix according to the number of occurrences:di-,tri-, tetra-,penta-,or hexa.Polydentate ligands (e.g., ethylenediamine,oxalate)receive bis-,tris-,tetrakis-,etc. ii)anions end in o.This replaces the final 'e'when the anion ends with '-ate',e.g.sulfate becomes sulfato.It replaces 'ide':cyanide becomes cyano
11.1.2. Names of complexes of various types 1. The basic procedure for naming a complex (英语命名 法)： ①When naming a complex ion, the ligands are named before the metal ion. ②Write the names of the ligands in alphabetical order. ⅰ) multiple occurring monodentate ligands receive a prefix according to the number of occurrences: di-, tri-, tetra-, penta-, or hexa. Polydentate ligands (e.g., ethylenediamine, oxalate) receive bis-, tris-, tetrakis-, etc. ⅱ) anions end in o. This replaces the final 'e' when the anion ends with '-ate', e.g. sulfate becomes sulfato. It replaces 'ide': cyanide becomes cyano
iii)neutral ligands are given their usual name,with some exceptions:NH3 becomes ammine;H2O becomes aqua or aquo;CO becomes carbonyl;NO becomes nitrosyl. 3 write the name of the central atom/ion.If the complex is an anion,the central atom's name will end in -ate,and its Latin name will be used if available (except for mercury). 4If the central atom's oxidation state needs to be specified (when it is one of several possible,or zero),write it as a Roman numeral (or 0)in parentheses. 5Name cation then anion as separate words(if applicable,as in last example)
