The magnetic ground state of the Heusler compound Mn${}_{2}$CoSn was predicted to be nearly half-metallic ferrimagnetic with a high spin polarization by ab initio electronic structure calculations. Mn${}_{2}$CoSn was synthesized, and the magnetic behavior of the compound was studied using a superconducting quantum interference device and x-ray magnetic circular dichroism. The experimental values were found to be in fair accordance with the theoretical predictions. The electronic structure and the crystal structure of Mn${}_{2}$CoSn were characterized comprehensively using x-ray powder diffraction, $^{119}\mathrm{Sn}$ M\"ossbauer spectroscopy, nuclear magnetic resonance, and hard x-ray photoelectron spectroscopy.
