The title compound with the nominal formula, Sr13Eu8Cd3Mn1Sb18, was synthesized by Sn-flux. Structure refinement was based on single-crystal X-ray diffractometer data. Employing the exact composition, the formula is Sr13.23Eu7.77Cd3.12Mn0.88Sb18 for the solid solution Sr21-xEuxCd4-yMnySb18. This phase adopts the Sr21Mn4Sb18 type structure with site preferences for both Eu and Cd. The structure crystallizes in the monoclinic system in space group C2/m and Z=4: A=18.1522(11), b=17.3096(10), c=17.7691(10) Å, β=91.9638(8)°, 6632 F2 values, 216 variables, R1=0.0254 and wR2=0.0563. Site selectivity of the elements in this new compound will be discussed in relationship with the Sr21Mn4Sb18 type structure and other related structure types. Temperature dependent magnetic susceptibility data reveal Curie-Weiss paramagnetism with an experimental moment of 19.3 μB/f.u. and a Weiss constant of 0.4 K. Magnetic ordering is seen at low temperatures, with a transition temperature of 3.5 K.
