ABSTRACT
The title compound, [Pt(C10H6NO2)Cl(C5H11N)], crystallizes with one mol-ecule in the asymmetric unit. The Pt(II) cation has a slightly distorted square-planar coordination environment defined by a chloride anion, the quinoline N atom and a carboxyl-ate O atom of the bidentate quinaldate ligand and a piperidine N atom. An intra-molecular C-H⋯Cl hydrogen bond occurs. In the crystal, mol-ecules are stacked into columns along the c axis by the formation of N-H⋯Cl and C-H⋯O hydrogen bonds.

fig1: View of the mol­ecular structure of the title compound, showing the atom-labelling scheme, with ellipsoids drawn at the 50% probability level. The intra­molecular C—H⋯Cl hydrogen bond is shown as a green dashed line.

Mentions: The title complex crystallizes with one mol­ecule per asymmetric unit (Fig. 1 ▶). The PtII cation is surrounded by two N atoms, one O atom and one Cl atom, resulting in a slightly distorted square-planar coordination environment [angles around platinum: O1—Pt1—N1 81.38 (9), O1—Pt1—N2 88.26 (9), Cl1—Pt1—N2 84.26 (7) and Cl1—Pt1—N1 106.11 (7)°]. The Cl− and the PtII atoms are displaced from the least-squares plane of the quinoline ring and all other coord­inating atoms by 0.2936 (7) and 0.0052 (1) Å, respectively. The piperidine ring adopts a chair conformation and is almost perpendicular to the coordination plane of the PtII cation [dihedral angle between the best plane through the piperidine ring and the four atoms coordinating to the PtII cation = 79.66 (13)°]. Bond lengths are normal and agree well with related platinum compounds (Cambridge Structural Database, version 5.34; Allen, 2002 ▶). There is an intra­molecular hydrogen bond between atom Cl1 and atom H8 (Fig. 1 ▶ and Table 1 ▶).
