Multi-component self-assembly of molecule based materials by coordination networks and weak intermolecular synthons

In English The coordination polymer Fe(SCN)(2)(1,2-bis(4-pyridylmethylene)hydrazine)(2)(n) Fe(phenanthroline)(3)(2n)(ClO4)(2n)center dot n1,2-bis(4-pyridylmethylene)hydrazine center dot 4nH(2)O 1 was crystallised from a MeOH/MeCN solution and the structure consists of layered (4,4) 2D-nets with supramolecular (Fe(phen)(3)(2)bphz)(4+) units in the pores and disordered water and perchlorate anions. The same supramolecular motif could be independently prepared as Fe(phen)(3)(2)center dot bphz(ClO4)(4)center dot xMeOH(2), and the Ru(phenanthroline)(3)(2+) compound 3, isostructural to 1, was also prepared although a complete structure determination was prevented by low crystal quality. Compounds 1 and 3 are rare examples of how several large and different components can be assembled inside a 2D coordination network and provide a concept for multi-component self-assembly.
