Pyridylphosphine supported Ag(I) and Cu(I) complexes for detection of alcohols and nitriles via structural transformations from 1D to 0D

Abstract

A series of coordination complexes: , [Ag2(PPh2Py)2(MeCN)4](ClO4)2·MeCN (1) [Ag2(PPh2Py)2(ClO4)2]n·2(CH2Cl2)n (2), [Cu2(PPh2Py)2(MeCN)2](ClO4)2 (3) and [Cu2(PPh2Py)2(ClO4)2]n (4), with diphenyl-2-pyridylphosphine (PPh2Py) are were synthesized and characterized by single X-ray crystallography. In the crystal structure, 2 and 4 form one-dimensional coordination polymers with perchlorate ion in the presence of bridging ligands. They exhibit strong luminescence in crystalline state but dramatically quenched when exposed to alcohol and or nitrile vapors. 1 and 3 are non-emissive 0 dimensional0-dimensional complexes with coordinating acetonitrile solvents. The structures of 1 and 3 reveal that alcohol or nitrile vapors could replace the bridging perchlorate ion in 2 and 4 so as to occupy the metal coordination sites. This structural transformations from 1D to 0D makes 2 and 4 as promising candidate materials for detection of alcohols and nitriles.
