Abstract
A compound of the general formula ##STR1## or a salt or complex thereof, in which X, Y and Z are all optionally substituted carbon atoms and R is hydrogen, optionally substituted hydrocarbyl or acyl or --COOR.sup.7 and R.sup.7 is hydrocarbyl has anti-microbial properties. Particular examples are compounds in which X is --CH.sub.2 -- or --C(CH.sub.3).sub.2 -- and Y and Z are both --CH.sub.2 -- or X is is --CH.sub.2 -- and Y and Z are carbon atoms of a benzene ring. The zinc complexes have useful properties.
