In the title RuII carboxylate compound, [Ru(C2H3O2)(C26H24P2)2](CF3O3S)0.75Cl0.25, the distorted tris-bidentate octahedral stereochemistry about the RuII atom in the complex cation comprises four P-atom donors from two 1,2-bis(diphenylphosphanyl)ethane ligands [Ru—P = 2.2881 (13)–2.3791 (13) Å] and two O-atom donors from the acetate ligand [Ru—O = 2.191 (3) and 2.202 (3) Å]. The disordered counter-anions are located on the same site in the structure in a 3:1 ratio, the expanded formula comprising four complex cations, three trifluoromethanesulfonate anions and one chloride anion, with two such formula units in the unit cell.

In the crystal structure of the title salt, C10H16N3O+·C7H5O2−, the cations and anions are linked to each other via N—H
O hydrogen bonds, forming infinite chains running along [010]. The crystal structure also features C—HO and π–π stacking interactions, which assemble the chains into supramolecular layers parallel to (100). The π–π stacking interactions are observed between the pyridine rings of inversion-related cations with a centroid–centroid distance of 3.867 (2) Å.

The asymmetric unit of the title compound, C14H22N4O2·0.25C6H14·0.5H2O, contains two independent molecules of 2,4-bis(pivaloylamino)pyrimidine (M) with similar conformations, one water molecule and one-half n-hexane solvent molecule situated on an inversion center. In one independent M molecule, one of the two tert-butyl groups is rotationally disordered between two orientations in a 3:2 ratio. The n-hexane solvent molecule is disordered between two conformations in the same ratio. The water molecule bridges two independent M molecules via O—HO, N—HO and O—HN hydrogen bonds into a 2M·H2O unit, and these units are further linked by N—HN hydrogen bonds into chains running in the [010] direction. Weak C—HO interactions are observed between the adjacent chains.
