Four novel coordination frameworks with high degree of diamondoid interpenetration containing scarce quadruple-stranded homo-axis helices and quintuple-stranded molecular braids

Four novel interpenetrated diamondoid (dia) networks obtained by self-assembly of a new long linear N-donor ligand and transition metal salts in the presence of short ditopic carboxylate ligands, provide an 8-fold [4+4] interpenetrated dia network containing the unique quadruple-stranded braid as well as an unprecedented octuple-stranded braid, and three 5-fold interpenetrating dia networks containing an exceptional quintuple-stranded molecular braid.
