摘要
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 P1 with a =8.458(3)angstrom, b= 11.016( 2), c =16.249( 3) (angstrom), alpha=94.630(14), beta=100.63(2), gamma =108.55(4)degrees 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+ . . . pi(Ph) interactions and N-H . . . O hydrogen bonds. The complex is compared with data for related structures.
