摘要：

Novel ionic compounds of the class [Fe{CO(NH2)2}n(H2O)6-n]++SO4-- wherein n is 2, 3, 4 or 5, are produced by solid state reaction between a ferrous sulfate hydrate and urea under extended intensive physical impingement conditions, as for example by ball milling for a period in excess of 2 hours, until particles of an unusual characteristic shape are formed. Uses of the compounds include correcting iron deficiencies in plants.
