The hydrothermal reaction of 5-benzylaminoisophthalic acid(H2BAIP) and Zn(CH3COO)2·2H2O in the presence of Na OH gave rise to a three-dimensional(3-D) metal-organic framework containing Zn(II)-carboxylate chains, [Zn(BAIP)]n. Single-crystal X-ray diffraction analysis reveals that the complex crystallizes in trigonal space group R-3 with a = 28.354(2), b = 28.354(2), c = 8.3821(8) , γ = 120 o, V = 5836.0(10) 3, Z = 18, Mr = 334.62, Dc = 1.714 g·cm-3, μ = 1.909 mm-1, S = 1.162, F(000) = 3060, the final R = 0.0785 and w R = 0.1121 for 2334 observed reflections(I > 2σ(I)). Zn(II) is in a distorted tetrahedral geometry, and BAIP serves as a μ4-bridge using two μ2,η2-bridging carboxylate groups. BAIP links Zn(II) ions into a 3-D network containing hexagonal cavities. The coordination-inert benzyl occupies the void space of the large hexagonal cavities. The complex is thermally stable up to 410 2, and exhibits photoluminescent emission at 522 nm on 402 nm excitation.
