New Nitrogen-containing Heterocyclic Bidentate Phosphine Ligands Of Cu (¢ñ) Synthesis

At room temperature, eight new copper(I) diphosphine complexes, [Cu2(dppm)2(C9H7N)Cl2] (C9H7N)2·H2O(1),[Cu2(dppm)2(i-C9H7N)Br2](C10H8)(C9H7N) CH3CN(2),{[Cu3(dppm)3Br2] [Cu2(dppm)(pyz)Br2]Br·(CH3OH)2}n(3),{[Cu2(dppm)2(NO3)2(pyz)](pyz)}n (4),{[Cu2(dppm)2X2 (pyz)](CH2Cl2)}n(X=ClO4 (5), BF4 (6)),{[Cu2(dppm)2(4,4'-bpy)2(CF3SO3)](CF3SO3)(CH3OH)}n (7),{[Cu2(dppe)2(phen)2](ClO4)2(CH2Cl2)}n (8) [dppm=bis(diphenylphosphino)methane, dppe= bis(diphenylphosphino)ethane, C9H7N=quinoline, i-C9H7N= iso-quinoline, C10H8=naphthaline, pyz=pyrazine , 4,4'-bpy=4,4'- bipyrimidine, phen=1,10-Phenanthroline], have been synthesized and characterized by elemental analysis, IR, NMR, luminescence, and X-ray structure determination. In these complexes, 1 and 2 are 0D dimers, 3 is a 1D sine-curve-like polymer, 4, 5 and 6 are 1D linear polymers, 7 is a 1D stair-shaped polymer, and 8 is a 1D W-shaped polymer.
