In the crystal structure of the title compound, 5-fluorocytosinium picrate, C4H5FN3O+·C6H2N3O7−, one N heteroatom of the 5-fluorocytosine (5FC) ring is protonated. The 5FC ring forms a dihedral angle of 19.97 (11)° with the ring of the picrate (PA−) anion. In the crystal, the 5FC+cation interacts with the PA−anion through three-centre N—H...O hydrogen bonds, forming two conjoined rings havingR21(6) andR12(6) motifs, and is extended by N—H...O hydrogen bonds and C—H...O interactions into a two-dimensional sheet structure lying parallel to (001). Also present in the crystal structure are weak C—F...π interactions.

The title compound, C11H9NO3, contains an isoxazole and a hydroxybenzylidene ring, which are inclined to each another by 3.18 (8)°. There is an intramolecular C—H...O contact forming an S(7) ring. In the crystal, molecules stack head-to-tail in columns along the b-axis direction, linked by offset π–π interactions [intercentroid distances of 3.676 (1) and 3.723 (1) Å]. The columns are linked by O—H...O and O—H...N hydrogen bonds, forming layers parallel to the ab plane. The layers are linked by C—H...O hydrogen bonds, forming a supramolecular three-dimensional framework. An analysis of the Hirshfeld surfaces points to the importance of the O—H...O and O—H...N hydrogen bonding in the packing mechanism of the crystal structure.

The crystal structure of the title compound, [Cd(C8H3FO4)(H2O)2] n , consists of polymeric sheets formed by the bridging of octahedrally coordinated CdII by carboxylate O atoms of the 3-fluorophthalate (3-fpt2−) ligand. The layers exhibit hydrogen bonding between each of two coordinated water molecules and two O atoms of the ligand. Adjacent sheets are connected through π–π interactions.

In the title compound, [Re(C10H6NO2)(C7H11N)(CO)3], the ReIatom is coordinated by three carbonyl ligands in a facial arrangement and by the N, O and C atoms from a chelating quinaldate anion and a monodentate isocyanide ligand, respectively. The resultant C4NO coordination sphere is distorted octahedral. A lengthening of the axial Re—CO bondtransto the isocyanide ligand is indicative of thetranseffect. Individual complexes are stacked into rods parallel to [001] through displaced π–π interactions. Weak C—H...O hydrogen-bonding interactions between the rods lead to the formation of layers parallel to (010). These layers are stacked along [010] by C—H...H—C van der Waals contacts.
