Abstract
Crystallisation of flexible dipyridyl ligands with either Zn(NO3)2·6H2O or Zn(ClO4)2·6H2O gave co-ordination networks of composition [Zn3(OH)3{(NC5H4)2C3H6}3][NO3]3·8.67H2O 1 [(NC5H4)2C3H6 = 1,3-bis(4-pyridyl)propane]; [Zn2(OH){(NC5H4)2C4H8}3][ClO4]3·H2O·EtOH 2 [(NC5H4)C4H8 = 1,4-bis(4-pyridyl)butane] and [Zn2(OH){(NC5H4)2C7H14}4][ClO4]3·0.5H2O 3 [(NC5H4)2C7H14 = 1,7-bis(4-pyridyl)heptane]. The compounds were characterised by X-ray single crystal diffraction studies. Compound 1 possesses a trinuclear Zn3(OH)3 6-membered ring that acts as a template for the co-ordination framework. Both 2 and 3 possess dinuclear zinc sub-units (Zn2OH) that contain a bridging hydroxyl ion.Keywords
