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

• The coordination polymer [Fe(SCN)2(1,2-bis(4-pyridylmethylene)hydrazine)2]n [Fe(phenanthroline)3]2n(ClO4)2n·n1,2-bis(4-pyridylmethylene)hydrazine·4nH2O 1 was crystallised from a MeOH/MeCN solution and the structure consists of layered (4,4) 2D-nets with supramolecular ([Fe(phen)3]2bphz)4+ units in the pores and disordered water and perchlorate anions. The same supramolecular motif could be independently prepared as [Fe(phen)3]2·bphz(ClO4)4·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.
