The reaction of K2PtCl4 with 3-amino-5-methyl-5-phenylhydantoin (amphh, L) and KI in aqueous ethanol yields dark violet crystals of a binuclear platinum(II) complex. The molecular structure of the complex was determined by single-crystal X-ray diffraction methods. The complex crystallizes in the triclinic space group [image omitted] with a = 8.458(3), b = 11.016(2), c = 16.249(3) (Å), α = 94.630(14), β = 100.63(2), γ = 108.55(4)° and Z = 2. The structure consists of [K2L4]2+ cations and [Pt2I6]2- anions bridged by K-I bonds to form quasi-one-dimensional chains along the b axis. Chains are linked by K+ ··· π(Ph) interactions and N-H ··· O hydrogen bonds. The complex is compared with data for related structures. [ABSTRACT FROM AUTHOR]
