REVIEW: ZINC(II) COMPOUNDS: CLASSIFICATION AND ANALYSIS OF CRYSTALLOGRAPHIC AND STRUCTURAL DATA

Abstract

Abstract Zinc has a relatively low abundance in nature (10−6 of the earth's crust) but the chemistry of zinc compounds has been extensively investigated, and the relation-ships between structure and biomedical activity are of major importance. Zinc appears to bc one of the more biologically important metals,1 second only to iron among the heavy metals (i.e. excluding sodium, potassium, magnesium and calcium).
