It is shown that the nature of halogen bonds in cyanogen halides and 4-halopyridines differs, still cooperativity in both systems results from interacting point-dipoles.

Dramatic synergistic cooperative effects between Be⋯F beryllium bonds and Cl⋯N halogen bonds in XYBe:FCl:N-base ternary complexes lead to changes in the halogen-bond type from traditional to chlorine-shared to ion-pair bonds.

The synthesis and properties of a series of oxovanadium(1V) carboxylates (i.e. salts of organic acids) are described. The complexes closely resemble each other in magnetic properties, the observed paramagnetism being abnormally low for oxo-vanadium(1V) in the temperature range 90-350 K, with a broad maximum around 200-250 K. After testing of all reasonable models, the magnetic properties are interpreted in terms of anisotropic (Ising) antiferromagnetic exchange along infinite linear chains of interacting spins. On the basis of this model and with the aid of infrared, e.s.r., and electronic spectra, the most probable molecular structure for the series of complexes can be given. In our interpretation of the evidence, the interactions are of the super-exchange type.

AbstractThe nitridom anganate(I) Ca{Li2[MnIN]2) (space group P4/mbm: a = 703.35(7), c = 383.19(6) pm; Z = 2) contains infinite linear chains 1∞=[MnIN2/22-] running along the [001] direction. The nitride species of the chains are further linked via three coordinated lithium to form planar 4.82-nets 2∞{Li2N24-} parallel (001). Ca2+ occupies the centers of the eight-membered rings of the planar nets. The 4.82-arrangement 2∞{Li2N24-} together with the stacking sequence ...AA... along [001] exhibit strong topological similarities with the anionic substructure 2∞[B2C22-] observed in the crystal structure of e.g. Ce[B2C2]
