title: Potassium trifluoro-[(Z)-3-(oxan-2-yl-oxy)prop-1-en-1-yl]borate monohydrate.
abstract: The title compound, K(+)·C(8)H(13)BF(3)O(2) (-)·H(2)O, which was obtained from the reaction of a modified form of Z-vinylic telluride via a transmetalation reaction with n-BuLi, crystallizes as K(+) and C(8)H(13)BF(3)O(2) (-) ions along with a water mol-ecule. The K(+) cation is surrounded by four anions, making close contacts with six F atoms at 2.659 (3)-2.906 (3) Å and with two O atoms at 2.806 (3) and 2.921 (3) Å in a distorted bicapped trigonal-prismatic geometry.
