摘要: Abstract Reactions of flexible polydendate ligand system dispiro-dipyridyloxy-cyclotriphosphazene (L) with a variety mercury(II) salts (HgX2) (X = I−, Cl−) afforded two one-dimensional coordination polymers, namely formulated as {[Hg(L)(I)2]}n (1) and {[Hg(L)(Cl)2]}n.(ACN)0,341 (2). The isolated crystalline compounds were structurally characterized by single crystal X-ray crystallography. structure analysis revealed that 1 2 crystallizes in the orthorhombic (space group Pccn) monoclinic P21/c), which L exhibited κ2N binding mode divalent Hg ions to form chain structures. central Hg2+ ion has distorted tetrahedral geometry. UV–Vis properties thermal stability complexes (1, 2) also investigated. experiments (titration continuous variation (Job’s plot) analysis) showed all spectrophotometric solution state supports complexes. According TGA analysis, polymers up 300 °C, but more than 2.
