چکیده    The spiro-compound 30h-spiro[indole-3,20-[1,3]benzothiazole-2(1h)-one (ibth2) was synthesized and its structure was determined using spectroscopic techniques (ftir, 1h nmr and mass) and x-ray crystallography. this ligand possesses different centers for coordination. reactions of [m(co)6], m =cr, mo or w with ibth2 in thf under reduced pressure were studied. for chromium a complex with molecular formula [cr(itp)2] was isolated; where itp is the opened form of the ligand which occurred through cspiro–s bond, while [mo(co)5(ibth2)] and [w(co)5(ibth2)] were isolated from the reaction of ibth2 with molybdenum and tungsten carbonyls, respectively. all complexes were characterized by elemental analysis, ir, mass and 1h nmr spectroscopy. the biological activity of the ligand and its complexes were studied and compared with the parent compound isatin.
