چکیده
The title compound, C(26)H(24)N(2)O(4), consists of a symmetrical mol-ecule that lies across a crystallographic inversion centre. The C-C distance in the triple bond is 1.188 (2) Å and there is also an inter-molecular C-H⋯O contact from a terminal acetyl-ene C-H to one of the dimiide O atoms [3.4349 (19) Å].

Supramolecular Coordination Polymers by Self-assembling of Bis-monodentate Ligands with HgI2
Two supramolecular coordination polymers, [HgI2(L )·0.5H2O]∞ (1) and [HgI2(L )·0.4CH3OH]∞ (2), have been prepared by ligands L 1 (L = bis[4-(4pyridylmethyleneamino)phenyl] ether) and L (L = N,N′-bis(3-pyridylmethyl)-diphthalic diimide) with HgI2, respectively. 1 formed an interestingly infinite cross-linked double helical structure, whereas 2 formed the one-dimensional zigzag chains, which are ...

Two new samples of poly(amide-imide)/nanocomposites containing bicyclo segment and dibenzalaceton moiety in the main chain were synthesized by a solution intercalation technique. Poly(amide-imide) (PAI) 8 as a source of polymer matrix was synthesized by the direct polycondensation reaction of N,N´-bis(4-carboxyphenyl)bicyclo[2,2,2]oct-7-ene-2,3,5,6-tetracarboxylic diimide 3 with 2,6-bis(4-amino...

متن کاملThe marriage of endo-cavity and exo-wall complexation provides a facile strategy for supramolecular polymerization.
Butylated pillar[5]arene (1) and N,N'-bis(n-butyl)pyromellitic diimide (2) form a 2 : 1 sandwich-type complex external to the walls of the receptor ("exo-wall" complex). The marriage of exo-wall interactions and endo-cavity inclusion provides a new strategy for the construction of supramolecular polymers from unfunctionalized neutral receptors.
