Triethylammonium benzene-1,3,5-tricarboxylato(pyridine)zinc(II): a two-dimensional undulating mesh network

A two-dimensional layered metal-organic framework material (HN(CH2CH3)3)Zn(BTC)(Pyd) with chiral trigonal pores has been prepared with HTEA+ as the structure-directing agent under mild synthetic condition. Crystal data for (HTEA)Zn(BTC)(Pyd): M=450.77, Orthorhombic, space group Pbca, a=13.652(4) Å, b=16.345(4) Å, c=18.734(6) Å, V=4180(2) Å3, T=293 K, Z=8, μ=1.213 mm−1, Dc=1.439 mg/m3. 9197 reflections measured, 2972 observed (Rint=0.0905), which were used in all calculations. The final R1=0.0498, Rω=0.1134. The structure was solved by direct methods using SHEUXTU-97.
