(6-Acetyl-1,3,7-trimethyllumazine-κ3O4,N5,O6)bis(triphenylphosphine-κP)copper(I) hexafluoridophosphate

Abstract

The title compound, [Cu(C11H12N4O3)(C18H15P)2]PF6, is the third example reported in the literature of a five-coordinated CuIP2NO2 system. The metal is coordinated to both PPh3 molecules through the P atoms and to the pyrazine ring of the lumazine molecule through an N atom in a trigonal–planar arrangement; two additional coordinated O atoms, at Cu—O distances longer than 2.46 Å, complete the coordination. The coordination environment can be described as an intermediate square-pyramidal/trigonal–bipyramidal (SP/TBP) polyhedron.
