NbAs2 crystal belongs to a larger family of transition metal dipnictides MPn2 (M = V, Nb, Ta, Cr, Mo, and W, Pn = P, As and Sb). It crystallizes in OsGe2 type structure which is monoclinic with the centrosymmetric space group of C12/m1. NbAs2 exhibit extraordinary physical properties including semi-metallicity, anomalous magnetoresistance, and other topological properties.
