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, [Zn2(aip)(Haip)2(H2O)2]⋅2H2O (1) and [Cu2(aip) (H2O)(μ3-OH)2] (2),were synthesized from the corresponding metal salts with 5-aminophthalic acid (H2aip) 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.
