5. Chemistry. The formation or existence of a co-ordinate bond; linking by means of a co-ordinate bond; frequently attributive, esp. in co-ordination number [translating German koordinationszahl (A. Werner 1893, in Zeitschrift für anorg. Chemie III. 326)] , (a) in a co-ordination compound, the number of atoms or groups linked to the central atom or group by co-ordinate or covalent bonds; (b) in a crystal, the number of ions immediately surrounding any given molecule or ion.
