1D Chains

A series of M(ii) coordination polymers has been synthesized. 1–3 contain 1D infinite chains, and these 1D chains are further linked by hydrogen bonding to form 3D supramolecular networks. While 4 and 5 show tetra- or penta-nodal 3D network, respectively.

Hydrogen Bonded

Four novel salts of chloranilic acid (H2CA; 3,6-dichloro-2,5-dihydroxy-1,4-quinone) with organic cations pyridinium (Hpy+), piperazinediium (H2ppz2+), 4,4'-bipyridinediium (H2bpy2+) and 1,10-phenanthrolinium (Hphen+) were prepared and structurally characterised: (Hpy)2CA (1), (H2ppz)CA (2), (H2bpy)CA·4H2O (3) and (Hphen)HCA·MeOH (4). Supramolecular architecture is based on extensive hydrogen bonding and π-stacking. The central motive is chloranilate dianion which acts as an acceptor of two bifurcated hydrogen bonds. Topology and dimensionality of hydrogen bonded networks can be tuned by use of different cations: thus discrete motives, 1D chains and 2D layers were observed. Three different types of π-stacks are present: aromatic stacks, quinoid stacks and stacks of alternating quinoid and aromatic rings.

1D Chains

Two bis-pyridyl-substituted α,β-unsaturated ketones were shown to form complexes with carboxylic acids and resorcinol derivatives. The neutral acid–acid homosynthon was observed in only one complex out of the five acid-bis-pyridyl containing complexes studied here, while the –COO−⋯HOOC– synthon was found to be dominant as it was observed in four complexes. The carboxylates self-assembled to form discrete dimeric, anionic, 1D chains and also exhibited mixed ionic hydrogen bonds. On the other hand, resorcinol derivatives displayed O–H⋯N hydrogen bonding to form tetrameric aggregates of bis-pyridyl ketone molecules and respective co-formers, while 3,5-dihydroxy benzoic acid (DHBA) molecules formed 1D chains by clipping two molecules of ketones with three DHBA molecules. Such clipping by the resorcinol derivatives promoted continuous π–π stacking interactions. Consequently, these materials emitted at higher wavelengths compared with the parent bis-pyridyl-substituted α,β-unsaturated ketones.
