In the crystal structure of the title compound, C11H10N2O3, inversion-related molecules are connected by pairs of O—H
O hydrogen bonds. With the exception of the atoms in the carboxylic acid group, the non-H atoms are roughly coplanar with a maximum deviation from the mean plane of 0.270 (1) Å for the C atom to which the carboxylic group is attached. The C atom of the carboxylic group lies 1.730 (2) Å from the mean plane.

The title compound, [Ni(C15H19BCl3N6)2] or Ni(Tp*Cl)2, adds to the list of structurally characterized bis(trispyrazolyl)borate-nickel(II) complexes. The two facially coordinating N-donor Tp*Cl ligands impose pseudo-octahedral coordination on the nickel(II) center. The asymmetric unit consists of two half molecules, primarily differing in the torsion angles of the coordinated pyrazole rings relative to the central B-Ni-B axis of the molecules; each molecule is centrosymmetric. An average overall Ni-N distance of 2.104 (15) Å is observed, typical of octahedral NiN6 coordination spheres and this class of compound. The title compound readily forms good quality crystals, while its 4-H analog, Ni(Tp*)2, does not. This characteristic is attributed to close contacts between the pyrazole 4-chloro-substituents on adjacent molecules.

metal-organic compounds
The title compound, [PtCl2(C14H16)], contains a square-planar d8 platinum(II) center which is coordinated by two Cl atoms and the double bonds of a rigid polycyclic ligand containing a 1,4-cyclooctadiene subunit. This compound is an interesting substrate for additional mechanistic studies of catalytically active metal complexes.

The title compound, C32H26Si, is a benzosilacyclopentene in which the silacyclopentene ring assumes an envelope conformation, with the Si atom displaced by 0.953 (2) Å from the mean plane of the four C atoms. The Si atom is bonded to two phenyl rings and to two Csp3 atoms in the silacyclopentene ring; one phenyl ring is attached to each of these two Csp3 atoms in the cis configuration.

In the title compound, C20H21N3O2·H2O (EQR·H2O), the quinazoline ring system forms dihedral angles of 53.1 (1) and 85.6 (1)° with the phenyl ring and the amide link, respectively. In the crystal, O—HO hydrogen bonds link two EQR and two water molecules into a centrosymmetric R44(18) ring motif. N—HO hydrogen bonds further link these hydrogen-bonded fragments into columns extending in [010].

The crystal structure of the title compound, C26H39BO2, which contains no strong hydrogen bond donors, displays only long C—HO contacts between inversion-related pairs of molecules. The structure contains layers rich in oxygen and boron parallel to the ac plane. The dioxaborinane ring adopts an envelope conformation with the C atom attached to the two methyl groups as the flap .

In the title compound, C19H21ClN2O2, the aromatic rings are approximately perpendicular to each other, subtending a dihedral angle of 87.7 (1)°. In the crystal, the 4-nitrophenyl groups of pairs of neighbouring molecules are parallel and oriented head-to-tail with a ring centroid–centroid distance of 3.9247 (12) Å, leading to a π–π interaction between the pair. The faces of each phenyl ring of the 2,6-diisopropylphenyl group interact with two different groups, viz. a chloro group of an adjacent molecule on one side and the edge of the 4-nitrophenyl ring of a second molecule on the other side.
