Crystal structure and Hirshfeld surface analysis of chlorido(2,6-dimethylphenyl isocyanide)[N′-(2,6-dimethylphenyl)-N-(pyridin-2-yl)carbamimidoyl]-platinum(II)

In the title compound, [Pt(C14H14N3)Cl(C9H9N)], the platinum atom has a square-planar geometry. In the crystal, dimers with R22(8) motifs are formed by pairs of N-H⋯N hydrogen bonds. They are connected to each other through pairs of weak C-H⋯Cl interactions, forming a R22(16) motif, creating parallel ribbons along the [011] axis. The molecular pairs are also linked by C-H⋯π and by π-π interactions, the shortest centroid-centroid distance [3.513 (2) Å] being observed between pyridyl rings. These weak interactions form parallel ribbons along the [010] axis. The resulting three-dimensional network ensures the cohesion of the crystal structure. Hirshfeld two-dimensional fingerprint plots revealed that the most significant interactions are H⋯H (58.0%), C⋯H/H⋯C (17.9%), Cl⋯H/H⋯Cl (10.7%), N⋯H/H⋯N (6.9%), C⋯C (2.9%), Pt⋯H/ H⋯Pt (2.6%), and N⋯C/C⋯N (1.1%) contacts. © 2025 Elsevier B.V., All rights reserved.
