A new novel tetrahalo-metallate was prepared by reaction of nicotinic acid with alkyl halide (1-bromododecane) to producing quaternary ammonium salt of nicotinic acid that acts as cationic surfactant then obtained on tetrahalo-metallate by adding metal chloride (copper chloride and cobalt chloride) and hydrazine sulfate enhances the activity of cationic surfactants to form the tetrahalo-metallate cationic surfactant. The effect of adding of polyurethane nonionic surfactants (PUNS) on the prepared compounds was studied for improvement of the biological activity and surface properties. The chemical structure for the synthesized compounds was characterized by using micro-elemental analysis, FTIR, 1H NMR, GPC and UV spectroscopy. The surface properties studied, contact angle and evaluation of these synthesized compounds as biocidal agents against some Gram-positive, Gram-negative bacteria, yeast, fungi and SRB (surface properties).
