In the title compound, [Pt(CHN)Cl(CHN)], the platinum atom has a square-planar geometry. In the crystal, dimers with (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 inter-actions, forming a (16) motif, creating parallel ribbons along the [011] axis. The mol-ecular pairs are also linked by C-H⋯π and by π-π inter-actions, the shortest centroid-centroid distance [3.513 (2) Å] being observed between pyridyl rings. These weak inter-actions 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 inter-actions 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.
在标题化合物[Pt(CHN)Cl(CHN)]中，铂原子具有平面正方形几何构型。在晶体中，通过N-H⋯N氢键对形成具有(8) motif的二聚体。它们通过弱的C-H⋯Cl相互作用对彼此相连，形成(16) motif，沿[011]轴形成平行的带状结构。分子对还通过C-H⋯π和π-π相互作用相连，吡啶环之间观察到最短质心-质心距离[3.513 (2) Å]。这些弱相互作用沿[010]轴形成平行的带状结构。由此产生的三维网络确保了晶体结构的凝聚性。 Hirshfeld二维指纹图谱显示，最显著的相互作用是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%)和N⋯C/C⋯N (1.1%)接触。
