Abstract: The tris(1H-benzimidazol-2-ylmethyl)amine (ntb) molecule crystallizes in different solvent systems, resulting in two kinds of adduct, namely the monohydrate, C24H21N7·H2O or ntb·H2O, (I), and the acetonitrile-methanol-water (1/0.5/1.5) solvate, C24H21N7·C2H3N·0.5CH4O·1.5H2O or ntb·1.5H2O·0.5MeOH·MeCN, (II). In both cases, ntb adopts a tripodal mode to form hydrogen bonds with a solvent water molecule via two N-H
O and one O-HN hydrogen bond. In (I), the ntb·H2O adduct is further assembled into a two-dimensional network by N-HN and O-HN hydrogen bonds, while in (II), a double-stranded one-dimensional chain structure is assembled via N-HO and O-HO hydrogen bonds, with the acetonitrile molecules located inside the cavities of the chain structure.
Formula: C24H21N7·H2O and C24H21N7·C2H3N·0.5CH4O·1.5H2O

If the supplementary material that you require is not shown in the list above, it may only be available in our hard-copy archive. However, our policy is to progressively digitize old hard-copy supplementary documents where possible.
Please help us to work towards this goal by completing the form below. This will register your wish to receive a supplementary document, which we shall scan to create a PDF and then make available via the web to you and to other requestors in the future.
