Microwave-Assisted Synthesis of Some New Mixed Ligand Ni(II) Complexes Its Characterization and Its Antimicrobial Study

Nickel(II) complexes of the type [Ni(P)(L)center dot 2H(2)O] has been synthesized by using 2-amino-6-methyl pyrimidine-4-ol (HP) and amino acids (HL). Complexes synthesized by conventional as well as microwave methods. Results indicate that complexes synthesized by the microwave method are more efficient than the conventional method. In the microwave method preparation time is short (47 min.) compared to the conventional method (45 min.). Moreover, the microwave Assisted method gives a very high yield (90%) of the complexes. The microwave method used for the synthesis of the complexes has been found easier, convenient and eco-friendly. Complexes have been characterized by FTIR, Elemental analysis, Gouy experiment, Thermogravimetric Analysis (TGA) and Differential Thermal Analysis (DTA). Complexes have shown significant antimicrobial activity.
