Two new 2D coordination polymers containing bowl-shaped voids assembled from the bis(chelating) bridging ligand

Two new coordination polymers, {[Mn-3(BIC)(3)(H2O)(4)]center dot C2H5OH center dot H2O}(n) (1) and {[Mn-3(BIC)(3)(H2O)(4)]center dot C3H6O center dot H2O}(n) (2, C3H6O = acetone), were obtained under hydrothermal conditions. Both of them are 2D networks containing bowl-shaped voids, which are occupied by EtOH and Me2CO molecules, respectively. Furthermore, the single 2D layer is chiral, which is assembled by the bis(chelating) bridging ligands and two kinds of Mn(II) coordination units. (C) 2011 Elsevier B.V. All rights reserved.
