The [nBu 3 Sn( N ‐phthaloylglycinate)(OH 2 )] compound has been prepared and characterized. The crystal structure reveals the tin atom, in each of the two molecules comprising the asymmetric unit, to exist in a distorted trigonal bipyramidal geometry in which the trigonal plane is defined by the three organic substituents and the axial sites are occupied by an oxygen atom derived from a monodentate carboxylate ligand and a coordinated water molecule. The [nBu 3 Sn( N ‐phthaloylglycinate)(OH 2 )] compound and three other triorganotin derivatives of N ‐phthaloyl‐protected amino acids display marked toxicity against several economically important plant pathogenic fungi.
