چکیده
The asymmetric unit of the title compound, C(17)H(12)O, contains two molecules, in which the fused aromatic ring systems are almost planar [maximum deviations = 0.0529 (9) and 0.0256 (9) Å]. In the crystal, aromatic π-π stacking inter-actions (perpendicular distance of centroids of about 3.4 Å) and strong O-H⋯O hydrogen bonds result in a helical arrangement of pyrenyl dimers.

Low-temperature redetermination of 4-chloro-2-[tris(hydroxymethyl)methyliminomethyl]phenol as zwitterionic 4-chloro-2-[tris(hydroxymethyl)methyliminiomethyl]phenolate
The title Schiff base, C(11)H(14)ClNO(4), originally refined as a neutral mol-ecule [Chumakov, Antosyak, Mazus, Tsapkov & Samus (2000), Crystallogr. Rep.45, 945-950], is inter-preted as a zwitterionic compound. There are two independent zwitterions in the asymmetric unit. Five of the six hydr-oxy groups of the -CH(2)OH fragments are disordered. In one zwitterion, two are disordered over three s...

The crystal structure of the title compound, C(6)H(11)NO(5), establishes the relative configuration at the four stereogenic centres; the absolute configuration is determined by the use of d-glucuronolactone as the starting material for the synthesis. Mol-ecules are linked by inter-molecular O-H⋯O and N-H⋯O hydrogen bonds into a three-dimensional network, with each mol-ecule acting as a donor an...

The title complex, [Ni(2)(C(4)H(8)N(4)O(2))(6)](NO(3))(4)·2CH(4)O, contains a centrosymmetric binuclear nickel(II) complex bridged by a pair of 4-amino-3,5-bis-(hydroxy-meth-yl)-1,2,4-triazole ligands. The separation between the Ni(II) atoms is 3.962 (1) Å. The Ni atoms are in a slightly distorted octa-hedral coordination. Inter-molecular N-H⋯O, N-H⋯N and O-H⋯O hydrogen bonds connect the ligand...

In the title compound, C(19)H(22)N(3)O(+)·Br(-), the imidazole ring is approximately coplanar with the pyridine ring [dihedral angle = 0.88 (13)°] and nearly perpendicular to the benzene ring [dihedral angle = 81.70 (13)°]. O-H⋯Br and C-H⋯Br hydrogen bonding helps to stabilize the crystal structure.
