Synthesis, Structure And Spectroscopic Properties Of Novel Copper(Ⅰ)/Sliver(Ⅰ) Compounds Containing Heterocyclic Triazole Ligands

This thesis focuses on the design of functional coordination compounds through the crystal structures and properties of series d¹⁰ Metal Complexes with N-Containing heterocyclic ligands. And discuss the relations between structures and photoluminescence of those compounds. The work provides some new methods and thoughts in the controlled design of functional coordination compounds. The thesis is divided into four chapters.In Chapter 1, the study background of this work is concisely introduced with the emphasis on classify of the metal-organic compounds and the current survey of N-Containing heterocyclic triazole coordination compounds. In addition, the meaning of this work was also described.In chapter 2, eight novel triazole-bridge Cu^I/Ag I phosphine compounds varying from monomer to two-dimensionality containing three triazole ligands and several P-donor auxiliary ligands have been synthesized. These traizole ligands include 1,2,3-triazole, 1,2,4-triazole, 3-Mercapto-1,2,4-triazole. Those compounds were determined by single-crystal X-ray diffraction. [Cu(l,2,4-Htrz)(PPh₃)₂I] (1) is a monomer compound with 1,2,4-triazole acting as a neutral ligand. [Cu(II)Cu(I)₄ (1,2,3-trz)₆(PPh₃)₄] (2), [Cu6(m-trz)₃(Htrz)₃(dppm)₆](BF4)₃ (3) are zero-dimensional oligomers with different coordination types of triazole ligands. 1,2,3-triazaole, as anion tridentate ligands, balance all charges of compound 2, and 1,2,4-triazole, not only act as anion tridentate ligands but as neutral monodentat ligands in 3. [Cu(1,2,4-trz)(PPh₃)-2]_n (4), {[Cu2(1,2,3-trz)L]I}_n (L=(Diphenyl(2-Pyridyl)phosphine) (5) are one-dimensional chains with bidentate and tridentate triazole ligands, respectively. [Cu2(1,2,4-trz)2dppe]_n (6),[Cu5(1,2,3-trz)₅(dppp)₂]_n (7), [Ag(Mtrz)PPh3]_n , (8) shows a two-dimensional structure with different coordination types of P-donor ligands. Herein, we selected five P-donor ligands, acting as auxiliary ligands, which have large steric hindrance because of so many phenyls and may serve in terminating roles, restricting the spatial extensions or limiting the dimensionality of the hybrid materials. In addition, the photoluminescence properties of six Cu(I) coordination polymers 1,2,4-7 in solid state have been studied.In Chapter 3, three novel Cu^I/Ag^I d¹⁰ metal complexes varying from one to three-dimensionality containing [1, 2, 4]triazolo[1, 5-a]pyrimidine (Tp) ligand have been...
