The title compound, [Bi(C8H18PS2)3], contains a BiIII cation surrounded by three bis(2-methylpropyl)dithiophosphinate anions, leading to a distorted octahedral coordination for the heavy metal. The Bi—S and S—P bond lengths are in the ranges 2.7694 (18)–2.8391 (17) and 2.019 (2)–2.035 (2) Å, respectively. The crystal structure is consolidated by C—HS hydrogen bonds. Intramolecular C—Hπ interactions also play a role in stabilizing the molecules.

The molecule of title compound, C13H11N5, is essentially planar (r.m.s. deviation = 0.0440 Å) and an intramolecular C—HN hydrogen bond generates an S(6) motif. In the crystal, molecules are connected into chains by intermolecular N—HN and C—HN hydrogen bonds. In addition, π–π stacking interactions are observed between the pyrazole and pyridazine rings [interplanar distance = 3.6859 (10) Å].

In the title compound, C16H14N4O2S, intramolecular N—HN hydrogen bonding forms an S(5) ring, whereas N—HO and C—HS interactions complete S(6) ring motifs. In the crystal, molecules form inversion dimers due to N—HO interactions. The dimers are interlinked through N—HS hydrogen bonds and π–π interactions occur with a centroid–centroid distance of 3.8422 (11) Å between the methoxy-containing benzene ring and the five-membered heterocyclic ring.

In the title compound, C15H11N5O3S, intramolecular N—HN hydrogen bonding forms an S(5) ring motif, whereas N—HO and C—HS interactions type complete S(6) ring motifs. The 2-oxoindoline and 3-methoxyphenyl rings are almost planar, with r.m.s. deviations of 0.0178 and 0.0149 Å, respectively, and form a dihedral angle of 33.59 (3)°. In the crystal, molecules are interlinked through the nitro groups in an end-to-end fashion via N—HO and C—HO interactions.

The asymmetric unit of title compound, C18H16O2, contains two molecules with slightly different conformations. In the first molecule, the two phenyl rings make dihedral angles of 84.98 (11)° and the five-membered ring makes dihedral angles of 84.80 (12) and 73.00 (12)° with the phenyl rings; the corresponding angles for the second molecule are 86.74 (11), 81.20 (13) and 71.36 (12)°. O—HO hydrogen bonds between the hydroxy and carbonyl groups are a feature of the crystal packing, which results in chains extending parallel to [100]. Weak C—HO and C—Hπ interactions are also observed.

The title compound, C8H8N2O4, is almost planar (r.m.s. deviation = 0.037 Å) and an intramolecular N—HO hydrogen bond generates an S(6) ring. In the crystal, inversion dimers linked by pairs of O—HO hydrogen bonds generate R22(8) loops. Intermolecular N—HO hydrogen bonds (involving the same H atom that forms the intramolecular hydrogen bond) link the dimers into infinite sheets lying parallel to (102).
