Synthesis and structure of two novel trans-platinum complexes

Here for the first time the synthesis and characterization of two new trans-platinum complexes, trans-[PtCl₂{HN=C(OH)C₆H₅}₂] (compound 𝟏) and trans-[with ᵗBu = C(CH₃)₃]{HN=C(OH)tBu}] (compound 𝟐) [with ᵗBu = C(CH₃)₃] are described. The structures have been characterized using nuclear magnetic resonance spectroscopy and X-ray single-crystal diffraction. In compound 𝟏 the platinum cation, at the inversion center, is in the expected square-planar coordination geometry. It is coordinated to two chloride anions, trans to each other, and two nitro­gen atoms from the benzamide ligands. The van der Waals interactions between the molecules produce extended two-dimensional layers that are linked into a three-dimensional structure through π...π intermolecular interactions. In compound 𝟐 the platinum cation is octahedrally coordinated by four chloride anions and two nitro­gen atoms from the pivalamide and ammine ligands, in trans configuration. The molecular packing is governed by intermolecular hydrogen bonds and van der Waals interactions.
