[(cot)PtX2](cot=(1,2,5,6-η)-1,3,5,7-cyclooctatetraene, X=Cl, I) was synthesized from a starting material, K2PtCl4. The reaction of alkyl or aryl Grignard reagents with [(cot)PtX2] yields a series of products which are the type of [(cot)PtR2] or [R2Pt(cot)PtR2](R=CH3, C6H5). An improved synthesis for [(cot)PtX2] complexes and the reaction with HI to give [(cot)PtRI] are described. The reaction of [(cot)PtR2](R=CH3) with K2PtCl4 yields cyclooctatetraene-Platinum dimer, [Cl2Pt(cot)PtR2]. The method of synthesis and formation mechanism of this series of compounds are introduced, the spectral data are discussed, and structure of this compounds are proposed.
