The journal has been established since January 1989 on a firm foundation of International Quality Research. Work describing new ligands or coordination geometries must provide sufficient evidence for the confident assignment of structural formulae; this will usually take the form of one or more X-ray crystal structures. Note: The impact factor shown here is equivalent to citescore and is, therefore, used as a replacement for the same. ROBERT H. CRABTREE, PhD, is a professor in the Department of Chemistry at Yale University. As the result of the interaction between the metal d and ligand orbitals, bonding, non-bonding and anti-bonding complex molecular orbitals are formed. In general, any element which corresponds to the d-block of the modern periodic table (which consists of groups 3-12) is considered to be … An ammonia (NH 3) complex of Ti and a transition metal was prepared in an organic solvent by the reaction of metal ions with ammonium; the complex then was dried in a vacuum oven, followed by nitridation in a tubular furnace under NH 3 flow. The impact factor (IF), also denoted as Journal impact factor (JIF), of an academic journal is a measure of the yearly average number of citations to recent articles published in that journal.
