The central NiII ion has an N5O octa­hedral coordination sphere defined by a tridentate 2,4,6-tris­(pyridin-2-yl)-1,3,5-triazine ligand, two SCN anions and a methanol ligand.

The organic–inorganic hybrid salt, [K(C8H12BO6)(H2O)0.5]n, is made up from a bis­(2-methyl­lactato)borate anion, a potassium cation and a half-occupied water mol­ecule.

The crystal structure of a biologically important pharmacophore containing 1,4-di­hydro­pyridine is reported.

The crystal structure is characterized by a range of inter­molecular inter­actions including C—H⋯F, C—H⋯Cl and C—H⋯O contacts. Aromatic π–π stacking between chromonyl groups and chloro­phenyl groups [centroid–centroid separations = 3.7170 (16) and 4.017 (2) Å, respectively] lead to columns of mol­ecules propagating parallel to the [100] direction.

The linked ring system is close to planar while the fluoro­phenyl group is almost perpendicular to the pyrazoyl ring. In the crystal, inversion dimers linked by pairs of C—H⋯S contacts are observed.

The asymmetric unit consists of two independent mol­ecules. In the crystal, the two independent mol­ecules form dimers linked by four C—H⋯O hydrogen bonds with each O atom accepting two such links.
