The first observation of nitrogen?carbonyl bonding: self-assembly of N-oxalyl 2,4-dinitroanilide assisted by a weak N?O?C interactionElectronic supplementary information (ESI) available: synthesis details and spectroscopic data for 1. See http://www.rsc.org/suppdata/cc/b3/b306012h/

A new type of weak bond, i.e., the N...O=C interaction, that determines the crystal packing of N-oxalyl 2,4-dinitroanilide (1) in cooperation with C-H...O hydrogen bonds, has been found and is rationalized by ab initio calculations as being the result of electrostatic interactions.

Hydrogen bond assisted helical self-assembly into [n]catenane

A [n]catenane supramolecular structure has been constructed by combination of metal-directed self-assembly with interligand hydrogen bonds which were confirmed by H NMR and DFT calculation.
