Abstract: The synthesis of tris(2,3- dihydroxynaphthaloto)silicate with different ammonium counter cations has been achieved both by conventional method and under microwave conditions using tetraethoxysilane. The compounds have been characterized using elemental analysis, IR, NM R (1H,13C and 29Si), and MALDI-TOF-MS techniques. Single crystal X –ray structure of [(n-C4 H9)3 NH)2][Si (C10H6O2)3] reveals a distorted octahedral geometry  around silicon and only discrete hydrogen bonding interaction between the ion pairs.
