摘要
Two coordination polymers, [Zn(CH3COO)(2)(INH)](n) (INH=isonicotinic acid hydrazid; isoniazid) (1) and [Zn(CH3COO)(2)(2-APy)](n) (2-APy=2-aminopyridine) (2) have been synthesized in DMF solution and structurally characterized by elemental analysis, IR spectra, single-crystal and powder X-ray diffractions. Structural analyses reveal that polymer 1 exhibits a 2-dimensional (2D) infinite layer framework, and the resulting 2D structure is interconnected by hydrogen-bond interactions to lead to a 3D supramolecular architecture. It crystallizes in the monoclinic system, space group P2(1)/c, with cell parameters a=0.914 44(17) nm, b=0.161 86(3) nm, c=0.871 75(16) nm, beta=96.181(3)degrees, V=1.282 8(4) nm(3), Z=4. Polymer 2 is an infinite 1D zig-zag chain. Polymer 2 crystallizes in the triclinic system, space group P (1) over bar, with cell parameters a=0.747 0(4) nm, b=0.814 5(5) nm, c=1.895 7(11) nm, alpha=88.276(8)degrees, beta=86.202(8)degrees, gamma=84.334(8)degrees, V=1.144 9(11) nm(3), Z=2. The solid-state luminescent properties of two polymers have also been investigated at room temperature. CCDC: 870030, 1; CCDC: 1524913, 2.
