In the title compound, the dihedral angle between the 2H-chromen-2-one ring system and the tert-butylacetate moiety is 72.72 (9)°. In the crystal, the molecules are connected through C—H⋯O hydrogen bonds, generating C(6) chains and R22(20) loops that are reinforced by weak aromatic π–π stacking interactions.

The title compound contains two almost coplanar phenyl rings and an intramolecular O—H⋯O hydrogen bond.
In the title compound, C16H14O3, the phenyl rings are oriented at a dihedral angle of 3.82 (3)° and an intramolecular O—H⋯O hydrogen bond closes an S(6) ring. In the crystal, weak C—H⋯O and C—H⋯π hydrogen bonds and aromatic π–π stacking occurs. A Hirshfeld surface analysis of the crystal structure indicates that the most important contributions for the crystal packing are from H⋯H (48.2%), H⋯O/O⋯H (20.0%), H⋯C/C⋯H (16.5%) and C⋯C (12.7%) interactions.

A layered crystal structure built up from alternating cationic and (anionic + water of crystallization) supramolecular planes parallel to (100) is described for the title hydrated salt.
The characterized organic trihydrate title salt, C17H17N4+·C7H5O5−·3H2O or (HL)+(Gal)−·3H2O, with L = 1,3-bis(1H-benzimidazol-2-yl)propane (C17H16N4) and HGal = 3,4,5-trihydroxybenzoic acid (gallic acid, C7H6O5), crystallizes with two formulas per asymmetric unit. One-half of the cations in the crystal feature a bent shape, with the central propyl chain having a gauche conformation, and the other half is nearly linear, with a trans propyl chain. Both cations form two independent herringbone layers in the crystal, which allow efficient π–π interactions between aromatic rings of the benzimidazole moieties. These layers are parallel to (100), and anions and water molecules of crystallization intercalate between these cationic planes. All potential donor groups for hydrogen bonding (NH and OH groups) actually form hydrogen bonds, ensuring a good cohesion between layers of cations and anions, stacked along [100].

The synthesis and single-crystal structure description of a silver(I) diphenyl-2-methoxyphenylphosphine nitrite complex is described.
The molecular structure of the title AgI complex, [Ag(NO2)(C19H17OP)2], is described, where a distorted tetrahedral coordination environment for the AgI atom is apparent within a O2P2 donor set as the nitrito anion coordinates in a bidentate mode. A fairly large angle for P—Ag—P [129.126 (16)°] is noted. The O—Ag—O chelate angle is = 50.38 (6)° and the P—Ag—O angles lie in the range 99.51 (5) to 118.45 (6)°. In the crystal, C—H⋯O interactions are evident.

The crystal structure of an arene ruthenium(II) complex bearing a bidentate Schiff base ligand is reported.
The asymmetric unit of the title compound, [RuCl(C7H8)(C12H9ClN2)]PF6, contains two cationic ruthenium(II) complexes and two [PF6]− anions. One of the anions exhibits disorder over two positions. The ruthenium complex adopts a piano-stool geometry, with chelating Schiff base and chlorido ligands occupying three coordination sites, and the arene ring serving as the ‘seat’.

In the title compound, [Fe(N3)2(C9H8N2)2]·H2O or [Fe(N3)2(AQ)2]·H2O, the FeII ion is distorted octahedrally coordinated by two azide ions in a cis position with a syn orientation, while the two amino groups of the AQ ligands are in a cis and the two pyridiyl N atoms are in a trans position.
In the hydrated title complex, [Fe(N3)2(AQ)2]·H2O (AQ is 8-aminoquinoline, C9H9N2), the FeII ion is coordinated in a distorted octahedral manner by two neutral, chelating AQ ligands and two anionic, monodentate azide (N3−) ions in a syn,cis-configuration. From the two AQ ligands, the pyridyl N atoms are opposite to each other and the amino groups trans to the azide ligands. Distortion results from different Fe—N bond lengths [2.112 (2)–2.231 (2) Å] and 〈(N—Fe—N)cis [75.25 (6)–99.91 (7)°] and 〈(N—Fe—N)trans [159.98 (7)–170.62 (7)°] bond angles. The water molecule acts as the acceptor of hydrogen bonds with the NH2 groups of both AQ-ligands in one and the same molecule, and as donor to the γ-N and α-N atoms of the azido ligands of two adjacent iron complexes. In addition, both terminal N atoms of the azido ligands are involved in hydrogen bonds with NH2 groups in neighboring iron complexes, so that the hydrogen-bonding pattern leads to a rod-like arrangement of the molecules in the b-axis direction.

A bischelated mononuclear nickel(II) complex with benzohydrazide ligands bearing an allyloxy group and a long saturated alkyl chain is reported.
The central NiII atom in the title complex, [Ni(C25H31N2O3)2], is located on crystallographic inversion center and adopts a slightly distorted square-planar coordination geometry defined by the imine nitrogen and amide oxygen donors of two chelating symmetry-related ligands in a trans configuration. The Ni—N and Ni—O bond lengths are 1.8685 (15) and 1.8409 (14) Å, respectively, with a chelating N—Ni—O bond angle of 83.79 (6)°. These data are in agreement with those determined for complexes of similar ligands.
