| Abstract: A 1D coordination polymer of [Cu(apy)(sal)2]n (apy=2-aminopyrimidine, sal=salicylaldehyde) has been synthesized and characterized by elemental analysis, IR, TG, UV, NMR, powder and X-ray single crystal diffraction. The title complex crystallized in triclinic system with space group P1, a=0.726 87(15) nm, b=0.914 41(18) nm, c=1.382 0(3) nm, α=108.74(3)°, β=94.13(3)°, γ=96.64(3)° and V=0.858 2(3) nm3, Z=2, R=0.087 8. Each Cu(Ⅱ) atom is six-coordinated by four O atoms from two different sal ligands and two N atoms from two different apy ligands, thus defining an octahedron coordination geometry. Adjacent Cu(Ⅱ) atoms are bridged by the apy ligands to construct a 1D zig-zag chain structure along the diagonal of bc plane with the closest Cu…Cu distance being 0.695 4 nm. Furthermore, such chains are further linked by π-π stacking interactions between the benzene rings of adjacent sal ligands into a 2D (4,4) layer structure. CCDC: 791023. |
