Complexes containing CO2 and SO2. Mixed dimers, trimers and tetramers.
Mixed dimers, trimers and tetramers composed of SO2 and CO2 molecules are examined by ab initio calculations to identify all minimum energy structures. While AIM formalism leads to the idea of a pair of C···O bonds in the most stable heterodimer, bound by some 2 kcal mol(-1), NBO analysis describes the bonding in terms of charge transfer from O lone pairs of SO2 to the CO π* antibonding orbital...
متن کاملCyclic metalloporphyrin dimers and tetramers: tunable shape-selective hosts for fullerenes.
Covalently linked cyclic metalloporphyrin dimers and tetramers have been demonstrated to be good shape-selective hosts for fullerene guests. The fullerene affinities of these hosts can readily be tuned by modulating the covalent linkage and the metal ions in the porphyrin subunits. A rigid Zn(porphyrin) dimer with conjugated bis(alkynyl) linkers exhibits a high selectivity towards C(70) over C(...
متن کاملPolar chemoreceptor clustering by coupled trimers of dimers.
Receptors of bacterial chemotaxis form clusters at the cell poles, where clusters act as "antennas" to amplify small changes in ligand concentration. It is worthy of note that chemoreceptors cluster at multiple length scales. At the smallest scale, receptors form dimers, which assemble into stable timers of dimers. At a large scale, trimers form large polar clusters composed of thousands of rec...
متن کاملC-16 artemisinin derivatives and their antimalarial and cytotoxic activities: syntheses of artemisinin monomers, dimers, trimers, and tetramers by nucleophilic additions to artemisitene.
Nucleophilic additions of lithium keto and ester enolates and mono- and bifunctional Grignard reagents to artemisitene provided C-16-derived artemisinin monomers, dimers, trimers, and tetramers whose antimalarial and cytotoxic activities have been evaluated.

MAC it happen : Presented is a study of the synergistic structuredirecting effect of metal–amine complexes (MACs) with different chelating polyamine ligands and imidazolium-based ionic liquid (IL) cations. For the first time, a layered selenidostannate with an asymmetric eight-membered ring, an organic-decorated layered selenidostannate, and a 3D selenidostannate with both the MAC and IL cation...
