Crystal Structure of Potassium Triflate‐butyrolactone, [K 3 (O 3 SCF 3 ) 3 (O 2 C 4 H 6 ) 2 ] Single Crystals of [K 3 (O 3 SCF 3 ) 3 (O 2 C 4 H 6 ) 2 ] ( 1 ) have been obtained as a by‐product from the reaction of KNPPh 3 with Yb(O 3 SCF 3 ) 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 μ 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, β = 100.623(7)°, R = 0.0484.
