Tetrakis(creatinine)platinum(II) Dithiocyanate

The structure of the title compound, tetrakis(2-amino-1,5-dihydro-1-methyl-4H-imidazol-4-one-N³)platinum(II) dithiocyanate, [Pt(C₄H₇N₃O)₄](SCN)₂, consists of [Pt(creat)₄]²⁺ (creat is 2-imino1-methyl-4-imidazolidinone) complex cations possessing approximate D₂ symmetry, and thiocyanate anions. The Pt atom has a square-planar coordination of four creatinine ligands bonded through their endocyclic N atoms. The Pt-N bond distances range from 1.980 (6) to 2.034 (7) Å. The creatinine molecules are planar and participate in inter- and intramolecular hydrogen bonds. The ligands are almost perpendicular to the equatorial PtN₄ plane.
