Under hydrothermal condition, the reaction of 3-hydroxy-1-adamantaneacetic acid (H2L) with CdCl2 and 1,3-di-4-pyridylpropane (dpp) has afforded a new Cd(Ⅱ) compound, [CdCl(HL)(dpp)(H2O)]n·nH2O (1), which was structurally characterized by single-crystal X-ray diffraction analysis. The crystal is triclinic, space group P1 with a= 1.091 0(1) nm, b=1.131 8(1) nm, c=1.246 4(1) nm, α=88.52(1)°, β=71.34(1)°, γ=68.11(1)°, V=1.345 2(1) nm3, Z=2, Mr=591.40, F(000)=608, Dc=1.460 g·cm-3, μ=0.947 mm-1, the final R=0.040 1 and wR=0.104 0 for 4 950 observed reflections (I>2σ(I)). Complex 1 consists of one-dimensional chains deriving from CdCl(HL)(H2O) units linked by dpp ligands, and lattice water molecules decorate between the chains. The O-H…O and O-H…Cl hydrogen bonds lead to the formation of a 2D layer structure.
A Zinc complex [ZnCl2(HL)2] with Schiff base HL derived from rimantadine and salicylaldehyde was synthesized and characterized by elemental analysis, infrared spectra, 1H NMR spectra,molar conductance, ultraviolet and visible spectra, thermal analysis. Its structure was determined by single crystal X-ray diffraction method. The complex, C38H50Cl2N2O2Zn, crystallizes in the orthorhombic system, space group Aba2 with a=1.381 7(3), b=2.275 0(5), c=1.145 0(2) nm, V=3.599(1) nm3, Z=4, Mr=653.79, F(000)=1 496, Dc=1.301 kg·m-3, μ(Mo Kα)=0.866 mm-1. The kinetic parameters were obtained from the analysis of TG curve by integral methods. The functions of thermal decomposition reaction mechanism are: F(α)=[1-(1-α)1/3]2, and kinetic compensation effect equation lnA=0.019 1E-0.142 7. CCDC: 253297.
