In the title compound, [Co(C5HF6O2)2(C9H8N2)], the CoII centre exhibits a pseudooctahedral coordination geometry, comprising two N-atom donors from the bidentate aminoquinoline ligand and four O-atom donor atoms from two bidentate chelating 1,1,1,5,5,5-hexafluoropentane-2,4-dionate ligands. In the crystal, molecules are linked via pairs of N—HO hydrogen bonds, forming inversion dimers. These dimers are further connected through π–π interactions between neighbouring quinoline rings [centroid–centroid distance = 3.472 (2) Å], and stack along the c axis.

In the title compound, [Mn(NO3)2(C12H8N2)2], the MnII atom lies on a twofold rotation axis, and is six-coordinated in a distorted trans-N4O2 octahedral environment by four N atoms from two 1,10-phenanthroline ligands and two O atoms from two nitrate anions. The nitrate anion is disordered about a twofold rotation axis with fixed occupancy factors of 0.5. In the crystal, molecules are linked by weak C—HO hydrogen bonds and π–π stacking interactions [centroid–centroid distance = 4.088 (5) Å] into a three-dimensional supramolecular network.

In the title polymer, [Cd(C5H3N2O2)(NO3)(H2O)]n, the CdII atom is seven-coordinate in a distorted capped octahedral geometry by two N atoms of two different pyrimidine dicarboxylate (pmc) ligands, three O atoms from three separate pmc ligands, and two O atoms of disordered nitrate anions or water molecules. The CdII atoms are bridged by the pmc ligands in a chelating/bridging bis-bidentate and chelating bidentate mode, forming sheets parallel to (20-1). The sheets are further linked into a three-dimensional supramolecular network via classical O—HO hydrogen bonds involving the nitrate anions and coordinating water molecules. Intramolecular O—HO hydrogen bonding is also observed. The non-coordinating nitrate O atoms are disordered over two sets of sites with occupancies of 0.57 (7) and 0.43 (7).
