Copper(II) biscomplexes of 3-bromo-6-chloro-8- quinolinol and 6-bromo-3-chloro-8-quinolinol were prepared, the long axes ofwhich were 16.8 A and 17.6 A respectively. The long axes of the pores in the walls of the test fungi were determined: A niger (15.0 A), A. oryzae (16.8 A), M verrucaria (17.4 A), T viride (15.0 A). M circinelloides (not determined), and T mentagrophytes (11 .4 A). When the long axis of the copper(II) complex was was shorter or equal to that of the pore, there was fungitoxicity. When the long axis of the complex was longer than that of the pore in the fungal wall there was no toxicity. This was due to penetration or exclusion from the cell
