We report enantiopure crystal growth and chiral helimagnetic ordering in chiral inorganic compounds CsCuCl3 with a chiral space group of right-handed P6122 or left-handed P6522. Our 2-step crystallization process makes it possible to grow centimeter sized enantiopure single crystals. Polarized neutron diffraction experiments probed that crystallographic chirality of CsCuCl3 strongly combined with helimagnetic chirality via Dzyalloshinskii-Moriya interaction.
