Potassium [(1S )-1-azido-2-phenylethyl]trifluoridoborate
The title compound, K+·C8H8BF3N3-, is a salt containing the chiral organic trifluoridoborate anion. The organic anions and potassium cations are tightly bound to each other by the coordination K-F [2.654 (3)-3.102 (3) Å] and K-N [2.951 (4)-3.338 (4) Å] interactions. Thus, the potassium cation adopts a nine-vertex coordination polyhedron, which can be described as a distorted monocapped tetragonal antiprism. In the crystal, the organic anions and potassium cations form layers parallel to (001). Weak C-H...[pi] interactions between neighbouring phenyl rings further stabilize the crystal.
