Two new coordination frameworks based on rod-shaped secondary building blocks with five-nodal (3,4,5,6)-connected and (3,5,6)-connected network topologies

Two new coordination frameworks, namely, [Zn-2(aip)(Haip)(2)(H2O)(2)]center dot 2H(2)O (1) and [Cu-2(aip) (H2O)(mu(3)-OH)(2)] (2),were synthesized from the corresponding metal salts with 5-aminophthalic acid (H(2)aip) under hydrothermal conditions. They possess interesting 3D architectures constructed from the rod-shaped secondary building blocks with 5-nodal (3, 4, 5, 6)-connected and (3, 5, 6)-connected network topologies, respectively. Moreover, luminescent behaviors of two complexes have been investigated at room temperature and they show the intense blue emissions. (C) 2011 Elsevier B.V. All rights reserved.
