1D and 2D metal-organic frameworks functionalized with free pyridyl groups

We show that a molecule constructed from an organic solid-state synthesis, namely, rctt-1,3-bis(2-pyridyl)-2,4-bis(4-pyridyl)cyclobutane (ht-2,4 '-tpcb) upon reaction with Cu(II) and Zn(II) ions gives one- (1D) and two-dimensional (2D) metal-organic frameworks (MOFs) of composition [Cu(hfac)(2)(2,4 '-tpcb-ht)](infinity) (where: hfac=hexafluoroacetylacetonate) (1) and [Zn(2,4 '-tpcb-ht)(2)(H2O)(2)](infinity)(2+), (2). Each MOF possesses uncoordinated, or free, 2-pyridyl groups that decorate the walls of each extended structure. (c) 2006 Elsevier B.V. All rights reserved.
