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...

CRYSTALS AND CRYSTALLINITY IN POLYMERS CRYSTALS AND CRYSTALLINITY IN POLYMERS Diffraction Analysis of Ordered and Disordered Crystals

Observation of two new conformers of neutral proline.

Using laser-ablation molecular-beam Fourier transform microwave (LA-MB-FTMW) spectroscopy two new conformers of proline have been identified together with the two previously observed (Angew. Chem. Int. Ed., 2002, 41, 4673).

Crystal engineering of mixed-metal Ru-Ag coordination networks by using the trans-[RuCl2(pyz)4] (pyz = pyrazine) building block.

In the rational development of new strategies for the crystal engineering of coordination networks[1] and of metal-based supramolecular architectures[2] the use of predetermined building blocks has assumed an increasing relevance in recent times. For example, molecular corners containing transition metals with programmed coordination angles, such as cisprotected PdII and PtII square-planar comp...
