Synthesis,Structure and Spectroscopic Properties of Novel 9,10-Bis {[6-(diphenylphosphanyl)-2-pyridylmethyl]propylaminomethyl} anthracene-Bridged Group 11 Metal (M = Cu~I and Ag~I) Dinuclear Complexes

摘要

Dinuclear complexes [M_2(mu-BPNNAn)]X_2 (M = Cu~I,X = C1O_4~- 1,X = BF_4~- 2;M = Ag~I,X = BF_4~- 3,X = ClO_4~- 4) have been prepared by treating 9,10-bis{[6-(diphenylphosphanyl)-2-pyridylmethyl]propylaminomethyllanthracene (BPNNAn) with M(CH_3CN)_4X in CH_2C1_2.The structures of complexes 1,2 and 3 have been determined by single-crystal X-ray diffraction studies.In the complexes,BPNNAn acts as a chelat-ing ligand and two metal ions riding on two bridgehead carbon atoms in the anthracene group leads to the deformation of the anthracenyl ring.The Cu-Arene charge transfer interaction is observed from the nonfluorescent emission of Cu complex 1,while the Ag complex 3 exhibits dual emission at high concentrations in a CH_2C1_2 solution.
