Naming Coordination Compounds
Naming Coordination Compounds Author: Kit Mao Department of Chemistry, Washington University St. Louis, MO 63130 For information or comments on this tutorial, please contact K. Mao at [email protected]. Please click here for a pdf version of this tutorial. A coordination complex is a substance in which a metal atom or ion accepts electrons from (and thus associates with) a group of neutral molecules or anions called ligands. A complex can be an anion, a cation ion, or a neutral molecule. Coordination compounds are neutral substances (i.e. uncharged) in which at least one ion is present as a complex. You will learn more about coordination compounds in the lab lectures for experiment 5 in this course. The coordination compounds are named in the following way. (At the end of this tutorial, there are additional examples that demonstrate how coordination compounds are named.) A. When naming coordination compounds, always name the cation before the anion. This rule holds regardless of whether the complex ion is the cation or the anion. (This is just like naming an ionic compound.) B. In naming the complex ion: 1. Name the ligands first, in alphabetical order, and then name the metal atom or ion. Note: The metal atom or ion is written before the ligands in the chemical formula. 2. The names of some common ligands are listed in Table 1. · Anionic ligands end in “-o.” For anions that end in “-ide”(e.g. chloride, hydroxide), “-ate” (e.g. sulfate, nitrate), and “-ite” (e.g. nirite), change the endings as follows: -ide ® -o; e.g., chloride ® chloro and hydroxide ® hydroxo -ate ® -ato; e.g., sulfate ® sulfato and nitrate ® nitrato -ite ® -ito; e.g., nitrite ® nitrito · For neutral ligands, the common name of the molecule is used (e.g. -

Introduction The Alfa Laval Black and Grey List is divided into three different categories: Banned, Restricted and Substances of Concern. It provides information about restrictions on the use of Chemical substances in Alfa Laval Group’s production processes, materials and parts of our products as well as packaging. Unless stated otherwise, the restrictions on a substance in this list affect the use of the substance in pure form, mixtures and purchased articles. - Banned substances are substances which are prohibited1. - Restricted substances are prohibited in certain applications relevant to the Alfa Laval group. A restricted substance may be used if the application is unmistakably outside the scope of the legislation in question. - Substances of Concern are substances of which the use shall be monitored. This includes substances currently being evaluated for regulations applicable to the Banned or Restricted categories, or substances with legal demands for monitoring. Product owners shall be aware of the risks associated with the continued use of a Substance of Concern. 2. Legislation in the Black and Grey List Alfa Laval Group’s Black and Grey list is based on EU legislations and global agreements. The black and grey list does not correspond to national laws. For more information about chemical regulation please visit: • REACH Candidate list, Substances of Very High Concern (SVHC) • REACH Authorisation list, SVHCs subject to authorization • Protocol on persistent organic pollutants (POPs) o Aarhus protocol o Stockholm convention • Euratom • IMO adopted 2015 GUIDELINES FOR THE DEVELOPMENT OF THE INVENTORY OF HAZARDOUS MATERIALS” (MEPC 269 (68)) • The Hong Kong Convention • Conflict minerals: Dodd-Frank Act 1 Prohibited to use, or put on the market, regardless of application.
