Crystal structure of (2-{3-[4-(4′-cyano­biphenyl-4-yl­oxy)but­oxy]pyridin-2-yl-κN}-5-(dodec­yloxy)phenyl-κC¹)(9-oxo­tetra­cos-7-en-7-olato-κ²O,O′)platinum(II)

The central Pt^II atom in the title compound, [Pt(C₄₀H₄₇N₂O₃)(C₂₄H₄₅O₂)], has a slightly distorted square-planar coordination environment. The dihedral angle between the plane formed by Pt and the chelating C and N atoms and that formed by Pt and the chelating O atoms is 2.1 (3)°. The angle between the planes of the two rings in the biphenyl-4-carbo­nitrile unit is 35.1 (5)°. One lateral alkane chain is disordered over two sets of sites with site occupancy factors in a 0.595 (7):0.405 (7) ratio.

Crystal structure of 6-eth­oxy­pyridin-1-ium-2-olate

In the title compound, C₇H₉NO₂, all non-H atoms are essentially coplanar [r.m.s. deviation = 0.032 Å]. The largest deviation from the plane of the pyridine ring is 0.105 (6) Å for the terminal C atom of the eth­oxy group. In the crystal, mol­ecules are linked by pairs of N—H...O hydrogen bonds, forming inversion dimers. These dimers are further linked by C—H...π inter­actions and weak π–π inter­actions between pyridine rings [centroid–centroid distance = 4.023 (1) Å].
