Abstract in another language

Single Crystals of K-3(O3SCF3)(3)(O2C4H6)(2)] (1) have been obtained as a by-product from the reaction of KNPPh3 with Yb(O3SCF3)(3) in THF with subsequent addition of butyrolactone, The structure of 1 consists of three symmetry-independent potassium ions which are linked by the oxygen atoms of the triflate ions and the butyrolactone molecules to give a supramolecular structure with layers normal to the crystallographic b-axis. The carbonyl oxygen atoms of both butyrolactone molecules show a mu (3)-bridging function between three K+ ions, one of them is, in addition, coordinated by the ring O-atom in a chelate manner, 1: Space group P2(1)/c, Z = 4, lattice dimensions at 193 K: a = 1155,0(1), b=1537.2(1), c= 1531.1(1) pm, beta = 100.623(7)degrees. R=0.0484.
