The intermetallic phase SrNi 2– x Sb 2 was synthesized by arc melting mixtures of the elements and subsequent annealing under argon, and its structure was investigated by means of both powder and single‐crystal X‐ray diffraction methods. It crystallizes with the ThCr 2 Si 2 type ( tI 10, I 4/ mmm ) and has a homogeneity range of x = 0.15(1)–0.28(1), which does not include the exact stoichiometric 1:2:2 composition. The crystal structure of the phase SrNi 2– x Sb 2 is built from layers of edge‐sharing Ni 1– x Sb 4 tetrahedra, which are separated by Sr atoms along the c direction. Magnetic measurements of SrNi 2– x Sb 2 showed no superconductive transition above 1.8 K.
