The asymmetric unit of the title compound, [Ni(C15H14NO2)2], comprises an NiIIcation, lying on an inversion centre, and a Schiff base anion that acts as a bidentate ligand. The NiIIcation is in a square-planar coordination environment binding to the imine N and phenolate O atoms of the two Schiff base ligands. The N- and O-donor atoms of the two ligands are mutuallytrans, with Ni—N and Ni—O bond lengths of 1.9191 (11) and 1.8407 (9) Å, respectively. The plane of the methoxybenzene ring makes a dihedral angle of 84.92 (6)° with that of the phenolate ring. In the crystal, molecules are linked into screw chains by weak C—H...O hydrogen bonds. Additional C—H...O hydrogen bonds, together with C—H...π contacts, arrange the molecules into sheets parallel to theacplane.

Crystals of the title compound, [Li{OOP(O-2,6-iPr2C6H3)2}(CH3OH)3]·CH3OH or [Li(C24H34O4P)(CH3OH)3]·CH3OH, have been formed in the reaction between HOOP(O-2,6-iPr2C6H3)2and LiOH in methanol. The title compound is of interest as it represents the first reported crystal structure of the family of lithium phosphate diesters. The {Li(CH3OH)3[O2P(O-iPr2C6H3)2]} unit displays the Li atom in a slightly distorted tetrahedral coordination environment and exhibits one intramolecular O—H...O hydrogen bond between a coordinating methanol molecule and the terminal non-coordinating O atom of the phosphate group. The unit is connected with two non-coordinating methanol molecules through two intermolecular O—H...O hydrogen bonds, and with a neighbouring unit through two other O—H...O interactions. These intermolecular hydrogen bonds lead to the formation of infinite chains along [100]. There are no significant interactions between the chains.

In the title compound, C7H14N4·2C6H5ClO, which crystallized with two crystallographically independent 4-chlorophenol molecules and one 1,3,6,8-tetraazatricyclo[4.3.1.13,8]undecane (TATU) molecule in the asymmetric unit, the independent components are linked by two O—H...N hydrogen bonds. The hydrogen-bond acceptor sites are two non-equivalent N atoms from the aminal cage structure, and the tricyclic system distorts by changing the C—N bond lengths. In the crystal, these hydrogen-bonded aggregates are linked into chains along thecaxis by C—H...N hydrogen bonds. The crystal structure also features C—H...π contacts.
