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

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).
