Abstract: First-principles calculations were performed to investigate electronic and elastic properties of the newly discovered 7.5 K superconductor: layered Nb2InC. As a result, electronic bands, total and site-projected $l$ – decomposed DOS at the Fermi level, shape of the Fermi surface for Nb$_2$In$_C$ were obtained for the first time. Besides, independent elastic constants, bulk modulus, compressibility, shear modulus, Young's modulus, Poisson's ratio together with the elastic anisotropy parameters and indicator of brittle/ductile behavior of Nb2InC were evaluated and analyzed in comparison with the available data.
