title: (6-Acetyl-1,3,7-trimethyl-lumazine-κO,N,O)bis-(triphenyl-phosphine-κP)copper(I) hexa-fluorido-phosphate.
abstract: The title compound, [Cu(C(11)H(12)N(4)O(3))(C(18)H(15)P)(2)]PF(6), is the third example reported in the literature of a five-coordinated Cu(I)P(2)NO(2) system. The metal is coordinated to both PPh(3) mol-ecules through the P atoms and to the pyrazine ring of the lumazine mol-ecule 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 inter-mediate square-pyramidal/trigonal-bipyramidal (SP/TBP) polyhedron.
