Ancillary ligand assisted self-assembly of coordination architectures of Mn(II): the effect of the N-alkyl group on a tridentate ligand

Dalton Trans., 2015, Advance Article
DOI: 10.1039/C4DT03005B, PaperSadhika Khullar, Sanjay K. Mandal
For the first time it is shown that a subtle change in the N-alkyl group (methyl or ethyl) of a tridentate ancillary ligand, bis(2-pyridylmethyl)alkylamine, is responsible for the diversity of product formation under similar conditions. Through their water vapor adsorption study, a structure-property correlation is established.

DOI: 10.1039/C4DT02573C, PaperVanessa Bellat, Remi Chassagnon, Olivier Heintz, Lucien Saviot, David Vandroux, Nadine Millot
Using TEM and EFTEM, we showed that titanate nanoribbons are made of an assembly of smaller ribbons juxtaposed and piled up on one another. We also studied their morphological, structural and chemical characteristics using XRD, Raman and XPS. New insights were obtained regarding their forming mechanism and structural integrity.
