In the title compound, [LaCl3(C12H8N2)2(C3H7NO)]·2C3H7NO, the LaIII ion is eight-coordinated by four N donors from two 1,10-phenanthroline ligands, one O atom from one N,N-dimethylformamide molecule and three chloride anions. In the crystal structure, the LaIII mononuclear units are linked to form a chain along the a axis by weak C—H...Cl hydrogen bonds. The chains are crosslinked to form a two-dimensional network parallel to the ab plane by π–π stacking interactions between the phen rings [centroid–centroid seperations range from 3.589 (2) to 3.708 (2) Å].

Hydrogen Bonded

In the crystal structure of the title organic proton-transfer complex, 2C12H11N2 +·C7H4O5S2−·3H2O, the cations form one-dimensional chains via intermolecular N—H...N hydrogen bonds and these chains, in turn, form a two-dimensional network through π–π stacking interactions. In addition, the anions and water molecules are connected into a two-dimensional hydrogen-bonded network through intermolecular O—H...O hydrogen bonds. The two motifs result in sheets of cations and anions stacked alternately.

In the title compound, C10H4BrFO3, a brominated and fluorinated 3-formylchromone derivative, all atoms are essentially coplanar (r.m.s. deviation of 0.025 Å for the non-H atoms), with the largest deviation from the least-squares plane [0.050 (6) Å] being for a benzene-ring C atom. In the crystal, molecules are linked through stacking interactions [centroid–centroid distance between the benzene and pyran rings = 3.912 (4) Å], C—H...O hydrogen bonds and short C...O contacts [2.865 (7) Å]. Unsymmetrical halogen...halogen interactions between the bromine and fluorine atoms [Br...F = 3.116 (4) Å, C—Br...F = 151.8 (2), C—F...Br = 154.1 (4)°] are also formed, giving a meandering two-dimensional network propagating in the (041) plane.
