Homologous size-extension of hybrid vanadate capsules - solid state structures, solution stability and surface deposition.

The dimensions and cavity sizes of the molecular capsules with the general formula [V10O18L4](10-) can be controlled modularly through the nature of the bifunctional, rigid organophosphonate ligands L(1) and L(2) (L(1) = bis(4-phosphonatophenyl)ethyne and L(2) = bis(4-phosphonatophenyl)butadiyne); the solution stability of the molecular entities as demonstrated by ESI-MS studies permits their assembly on the Au(111) surface on a sub-monolayer scale giving rise to a 2D supramolecular structure that is comparable to the packing arrangements of the capsules in the crystal structures.

{4,6-Bis[(E)-1-methyl-2-(pyridin-2-yl-methyl-idene)hydrazinyl]pyrimidine-κN,N',N''}dichloridomanganese(II).

In the title compound, [MnCl(2)(C(18)H(18)N(8))], the geometry around the Mn(II) centre is distorted square-pyramidal. In the crystal structure, mol-ecules pack via weak C-H⋯N and C-H⋯Cl inter-actions.
