Abstract
Crystals of N-3-pyridinyl-methanesulfonamide, PMSA (monoclinic, P21/c, a = 5.6436(7), b = 33.875(4), c = 8.3356(10) Å , β = 96.885(2)°) contain two non-equivalent molecules differing considerably in their conformations. The structure is stabilized by a network of hydrogen bonds, the strongest one being between the pyridine N atom and the sulfonamide H atom. Crystals of trans-[Pt(PMSA)2I2] (monoclinic, C2/c, a = 22.912(2), b = 5.2397(5), c = 17.3376(17) Å , β = 92.631(2)◦) contain centrosymmetric complex molecules in which PMSA is coordinated via the pyridine N atom, and Pt has a planar coordination. A system of hydrogen bonds of the types N−H· · ·O and C−H· · ·O links the complex molecules.
