Inside the anion, the mean planes with the protonated carboxylate groups kind dihedral angles of 11.0 (5), four.4 (five) and 80.three (4) together with the benzene ring to which they’re attached. The imply plane on the deprotonated carboxylate group types a dihedral angle of ten.six (5) with the benzene ring. Inside the crystal, the anions are involved in carboxylic acid O–H?? carboxyl hydrogen bonds, producing a two-dimensional network parallel to (001) containing R4(28) four and R4(32) motifs. The 2,9-dimethyl-1,10-phenanthrolinium four cations and water molecules reside between the anion layers and are connected towards the anions by means of N–H?? water and Owater–H?? carboxyl hydrogen bonds. An intramolecular O– H?? hydrogen bond can also be observed inside the anion.RefinementR[F two two(F 2)] = 0.088 wR(F 2) = 0.272 S = 1.00 4346 reflections 316 parameters three restraints H-atom parameters constrained ? ax = 0.37 e A? ? in = ?.40 e A?Table?Hydrogen-bond geometry (A, ).D–H??
