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.

In the title compound, [Cu(CH3COO)2(C9H8N2O)2]n, the CuIIion resides on a centre of inversion, displaying a tetragonally distorted octahedral coordination environment defined by two pairs of N and O atoms of symmetry-related 4-(1H-imidazol-1-yl)phenol ligands and the O atoms of two symmetry-related acetate ligands. The bridging mode of the 4-(1H-imidazol-1-yl)phenol ligands is associated with a very long Cu...O interactions involving the phenol O atom of the heterocyclic ligand, which creates chains extending parallel to [100]. In the crystal, the chains are arranged in a distorted hexagonal rod packing and are linkedviaC—H...O hydrogen bonds and by π–π stacking interactions involving centrosymmetrically related pairs of imidazole and phenol rings.

The title compound, [Co(C18H37N2)2(NCS)4], consists of a cobalt(II) ion positioned on the origin of the triclinic unit cell. It is coordinated by the N atoms of two trans-oriented 1-dodecyl-4-aza-1-azoniabicyclo[2.2.2]octane (DABCO+) cations, which carry n-dodecyl chains at the non-coordinating N atoms. The distorted octahedral coordination environment of the CoII ion is completed through four N atoms of isothiocyanate ions, which are arranged within the equatorial plane. Non-classical hydrogen bonding of the types C—H...N and C—H...S between the filamentous molecules lead to the formation of layers parallel to (001).

The average Fe—O(oxalate) bond length [2.00 (2) Å] is shorter than the average Fe—O(water) bond length [2.027 (19) Å]. The ionic components are connectedviaintermolecular N—H...O and O—H...O hydrogen bonds into a three-dimensional network.

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 title compound, [Ni(C6H4NO2)2(C16H38N6)], was prepared through self-assembly of a nickel(II) azamacrocyclic complex with isonicotinic acid. The NiIIatom is located on an inversion center and exhibits a distorted octahedral N4O2coordination environment, with the four secondary N atoms of the azamacrocyclic ligand in the equatorial plane [average Ni—Neq= 2.064 (11) Å] and two O atoms of monodentate isonicotinate anions in axial positions [Ni—Oax= 2.137 (1) Å]. Intramolecular N—H...O hydrogen bonds between one of the secondary amine N atoms of the azamacrocyclic ligand and the non-coordinating carboxylate O atom of the anion stabilize the molecular structure. Intermolecular N—H...N hydrogen bonds, as well as π–π interactions between neighbouring pyridine rings, give rise to the formations of supramolecular ribbons extending parallel to [001].
