We report here the sysnthesis and discovery of a new superconductor potassium distannide KSn2. KSn2 has a hexagonal crystal structure with a space group of P63 /mmc, which is called the MgZn2-type (C14) structure belonging to the famous family of Laves phases. The calculated lattice constants a and c are 0.6427(4) and 1.043(6) nm, respectively. From the magnetic susceptibility measurement, KSn2 shows a superconducting transition at around 3.2 K.
