Through Diffusion

The title compound [Na3(C11H6NO3)2(C2H3O2)]n, crystallized through diffusion of diethyl ether into methanol as needles. There are three crystallographically independent Na+cations present, each exhibiting a distorted octahedral coordination geometry, two through coordination by five O atoms and one N atom, and one through coordination by six O atoms. A series of intermolecular O...Na and N...Na contacts leads to the formation of chains along thea-axis direction.

The title compound, [Zr2Cl8(C6H6ClN)2], is centrosymmetric. Each ZrIV ion has distorted octahedral coordination geometry, formed by one N atom from a 4-chloroaniline ligand, three terminal Cl− ions and two bridging Cl− ions. The Zr—μ-Cl bond distances are much longer than the other Zr—Cl bond distances.

The title compound, [CoCl2(C6H7N)2(C2H6O)2], was obtained unintentionally as the product of an attempted synthesis of a polycarboxylate-bridged network complex of cobalt(II) using aniline as a base to deprotonate the organic acid. The molecule is centrosymmetric, so pairs of equivalent ligands lie trans to each other in a slightly distorted octahedral coordination geometry. Molecules are linked by O—H...Cl and N—H...Cl hydrogen bonds involving all the potential donors, generating sheets parallel to (001). The phenyl rings protrude on both sides of these sheets and have normal hydrophobic contacts with each other, involving no intercalation or stacking interactions.

In the title compound, [Cu(NO3)2(C5H6N2)4], the CuIIion is located on an inversion centre. It features a Jahn–Teller-distorted octahedral coordination geometry, defined by four N atoms of four 1-vinylimidazole ligands in the equatorial plane and two nitrate O atoms in the axial positions. The nitrate anion is disordered over two sets of sites in a 0.801 (6):0.199 (6) ratio. In the crystal, the complex molecules are linked by weak intermolecular C—H...O and C—H...π interactions.

The title compound [Co(C22H26N4O4)]PF6, commonly known as [Co(bpcd)]PF6, where bpcd2−is derived from the historical ligand nameN,N′-bis(2-pyridylmethyl)-trans-1,2-diaminocyclohexane-N,N′-diacetate, crystallized by slow evaporation of a saturated acetonitrile solution in air. The cation of the hexafluoridophosphate salt has the CoIIIatom in a distorted octahedral coordination geometry provided by an N4O2donor atom set. The acetate groups, which are oriented trans with respect to each other, exhibit monodentate coordination whereas the pyridyl N atoms are coordinating in a cis configuration. The geometry of the cation is compared to the geometries of other diamino diacetate complexes with CoIII.
