In the title polymeric ZnII compound, [Zn(C8H7O3)2(C12H12N2)] n , the Zn cation is coordinated by two N atoms from 1,2-bis(pyridin-4-yl)ethane unit and four O atoms from two mandelate [or hydroxy(phenyl)acetate] anions in a slightly distorted octahedral coordination geometry. The 1,2-bis(pyridin-4-yl)ethane unit bridges two ZnII cations, related by an inversion centre, to form a polymeric chain along [110]. The crystal structure features extensive O—H...O and weak C—H ...O hydrogen bonds, with C—H ... π interactions and π–π interactions also being present. The centroid–centroid distance between the phenyl ring of the mandelate group and the 1,2-bis(pyridine-4-yl)ethane moiety is 4.951 (2) Å. The 1,2-bis(pyridin-4-yl)ethane ligand is disordered over two positions, with a refined occupancy of 0.578 (14) for the major component.

Title Molecule

The title molecule, [Ir(C14H14FN2O)2(C5H7O2)], is located on a twofold rotation axis, which passes through the IrIIIatom and the central C atom of the pentane-2,4-dionate anion. The IrIIIatom adopts a distorted octahedral coordination geometry, beingC,N-chelated by two 2-tert-butoxy-6-fluoro-3-(pyridin-2-yl)pyridin-4-yl ligands andO,O′-chelated by the pentane-2,4-dionato ligand. The bipyridinate ligands, which are perpendicular to each other [dihedral angle between the two least-squares planes = 89.95 (5)°], are arranged in acis-C,C′andtrans-N,N′fashion relative to the central metal cation. Intramolecular C—H...O and C—H...N hydrogen bonds and intermolecular C—H...F hydrogen bonds as well as π—π interactions between neighbouring pyridine rings [centroid–centroid distance 3.680 (1) Å] contribute to the stabilization of the molecular and crystal structure, respectively.

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.

Benzene Rings

In the title compound, [Co(C14H8O5)(C12H8N2)]n, the CoIIatom is six-coordinated in a distorted octahedral coordination geometry by four O atoms from two chelating carboxylate groups from different 2,4′-oxydibenzoate anions and by two N atoms from a 1,10-phenanthroline (phen) ligand. The two benzene rings of the 2,4′-oxydibenzoate ligand form a dihedral angle of 77.14 (16)°. Adjacent CoIIatoms are bridged by 2,4′-oxydibenzoate anions to form a helical chain that propagates along theb-axis direction. Neighboring chains are further assembled by intermolecular π–π stacking interactions between inversion-related phen ligands [centroid-to-centroid distance = 4.0869 (8) Å] to form a two-dimensional supramolecular architecture.

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.
