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.

The molecule of the title compound, [NiZnBr2(C17H16N2O2)(C6H7N)2], contains a heterodinuclear arrangement. The two metal ions are bridged via phenol O atoms of the propane-1,3-diylbis(nitrilomethylidyne)]diphenolate (salpd2−) ligand. The two bridging O atoms of salpd2− and two Br atoms constitute a distorted tetrahedral coordination environment around the ZnII ion, while the NiII ion has a distorted octahedral coordination environment formed by two O and two N atoms of salpd2− in the equatorial plane and two N atoms of two 4-methylpyridine ligands in the axial positions. In the crystal structure, weak intermolecular C—H...Br hydrogen bonds link the molecules into chains along the c axis. Weak intramolecular C—H...O and C—H...N hydrogen bonds are also present.

Distorted Tetrahedral Coordination

In the title compound, [Cu(C4H12P2S2)2]BF4, both diphosphine disulfide molecules bind to the CuIatom, as chelating ligandsviathe S atoms, forming a monovalent cation with a slightly distorted tetrahedral coordination around the CuIatom. The average Cu—S distance is 2.350 (15) Å, with small but possibly significant differences within each chelate ring. Ligand P=S distances average 1.964 (3) Å, and the P—P distances are 2.2262 (13) and 2.2166 (14) Å. The ligand chelate rings are twisted in opposite directions, with one in the λ and one in the δ configuration. Although the anisotropic displacement parameters of the F atoms of the anion are quite large compared to that of the B atom, difference Fourier syntheses indicate only one set of sites for the F atoms. In the crystal, possible C—H...F hydrogen bonds may stabilize the orientation. The B—F distances, uncorrected for libration, average 1.359 (6) Å.

Distorted Tetrahedral Coordination

The title compound, [Zn2(C21H25N2)2(OH)2], is a binuclear zinc complex formed by two bidentate β-diketiminate (nacnac) ligands and two μ-hydroxide O atoms, bridging two mononuclear units into a centrosymmetric dimeric unit. Each Zn2+cation is coordinated by two N-donor atoms from the nacnac ligand and two O-donor atoms of hydroxide anions to give a distorted tetrahedral coordination environment. The Zn—O bond lengths are 1.9643 (13) and 2.0022 (14) Å, and the two Zn—N bond lengths are 1.9696 (14) and 1.9823 (14) Å. The distance between the two Zn2+cations in the dimer is 2.9420 (4) Å. Although hydroxide groups are present in the complex, no classical hydrogen-bonding interations are observed because of the bulky β-diketiminate ligands.
