Synthesis, crystal structure, and properties of a three-dimensional coordination polymer [Cd(PMP)2] n

Abstract

A new Cd(II) coordination polymer, [Cd(PMP) 2 ] n (1) [PMP = 1-phenyl-3-methyl-5-pyrazolone], has been synthesized by the reaction of Cd(CH 3 COO) 2 Á2H 2 O with PMP and characterized by elemental analysis, IR spectrum, fluorescence spectrum, UV-vis spectrum, TG-DTA, and electrochemical analysis. Single crystal X-ray diffraction reveals that the complex has a three-dimensional network. Each PMP acts as bidentate bridging ligand and each Cd(II) center is surrounded by two O atoms and two N atoms from four different PMP ligands to form distorted tetrahedral coordination geometry. The photoluminescence study shows the complex exhibited strong solid state blue fluorescent emission at room temperature, and the TG-DTA analysis demonstrated that it has highly thermal stability. Furthermore, the electrochemical property of the complex has been investigated for the first time in DMF by cyclic voltammetry, and the results showed that it has an irreversible process.

Interplay of thermochemistry and Structural Chemistry, the journal (volume 21, 2010) and the discipline

“…Synthesis, characterization, and X-ray single crystal structure determination of a new 3D Cd(II) coordination polymer, [Cd(PMP) 2 ] n (PMP = 1-phenyl-3-methyl-5-pyrazolone) is reported in the experimental paper by Xu et al [270]. Each Cd(II) is four-coordinated with a distorted tetrahedral geometry and linked by four PMP molecules that act as bidentate bridging ligands.…”

Synthesis, Crystal Structure, and Properties of the First Organomercury Dimer Derived from PMP

“…Just like other ligands containing N and O donors, PMP can display several different coordination modes15–19. For many years, we have been interested in the construction of metal complexes derived from PMP, and synthesized some PMP complexes such as [Zn(PMP) 2 Cl] n ,15 [Cd(PMP) 2 ] n ,16 and [Cd 2 (PMP) 2 Cl 4 ] n 17. As a continuation of our work, we have prepared another novel organomercury compound, [Hg 2 (PMP)Cl 2 ] 2 · DMF ( 1 ).…”

Alkali metal halogenides coordination compounds with hexamethylenetetramine

“…The research of compounds containing these cations, their ionic antagonists (like other alkaline metals) with anions existing in body fluids is thus of great importance, as they affect the sodium-potassium pump. In addition, recently, an increasing interest is put on construction of dinuclear, multinuclear and polymeric coordination compounds [24][25][26][27] created by self-assembly [28] of the components [29][30][31][32].…”
