Synthesis, Crystal Structure of catena-poly [[4,4′-bipyridine-N,N′-bis[(triphenylphosphine)-copper(I)]-pyridine-2-carbaldehyde azine-N,N′:N″,N′″] bis(tetrafluoroboride)]

AbstractThe title complex [Cu 2 (C 10 H 8 N 2 )(C 12 H 10 N 4 )(C 18 H 15 ) 2 (BF 4 ) 2 ] n has been synthesized and characterized by single crystal X-ray analysis. The compound crystallizes in the monoclinic space group P2 1 /c with a = 10.450(4) Å, b = 14.027(5) Å, c = 18.950(6) Å, β = 100.459(5)°, V = 2,731.7(16) Å 3 . In the title complex, the cation forms a linear chain, which is bridged by 4,4′-bipyridine and pyridine-2-carbaldehyde azine. The crystallographic asymmetry unit could be expanded polymeric structure using symmetry code: x, 1 + y, z; 1 − x, −y, 1 − z. The Cu(I) atom is coordinated by one P atom of PPh 3 ligand, two N atoms of pyridine-2-carbaldehyde azine ligand and one N atom of 4,4′-bipyridine ligand. There is a crystallographic centre of symmetry at the mid-point of the C-C bond between two pyridine rings of 4,4′-bipyridine.Graphical AbstractA linear chain complex [Cu 2 (C 10 H 8 N 2 )(C 12 H 10 N 4 )(C 18 H 15 ) 2 (BF 4 ) 2 ] n has been synthesized and characterized by single crystal X-ray and chemical analysis.[IMAGE]
