This work focuses on the structure and physical properties of the solid solution Ba 2 Co 1-x Zn x S 3 (0 ≤ x ≤ 1), a family of quasi-one-dimensional sulfides with end members Ba 2 CoS 3 and Ba 2 ZnS 3 . The structure of selected compounds with increasing Zn 2+ content has been analyzed using neutron diffraction, transmission electron microscopy, and extended X-ray absorption fine structure, and the physical properties have been analyzed via magnetic susceptibility and resistivity measurements. The progressive substitution of the nonmagnetic Zn 2+ cation for Co 2+ rapidly destroys the antiferromagnetic transition present at 46 K in the quasi-one-dimensional Ba 2 CoS 3 , leading to paramagnetic behavior down to the lowest investigated temperature (5 K) for compounds with x &gt; 0.25. For compounds with x ≥ 0.4, a pure Curie-Weiss regime is recovered around 300 K, yielding effective moments consistent with the g factor of the tetrahedrally coordinated Co 2+ previously determined for Ba 2 CoS 3 . The substitution of Zn 2+ for Co 2+ also removes the metallic-like behavior of Ba 2 CoS 3 , causing an increase in the value of the resistivity with all the Ba 2 Co 1-x Zn x S 3 compounds showing semiconducting behavior. The negative magnetoresistance of Ba 2 CoS 3 is improved by the substitution of Zn 2+ for Co 2+ , with values of -6% for Ba 2 Co 0.75 Zn 0.25 S 3 , -9% for Ba 2 Co 0.5 Zn 0.5 S 3 , and -8% for Ba 2 Co 0.25 Zn 0.75 S 3 . However, there does not seem to be a correlation between the values of resistivity and magnetoresistance and the content of Zn 2+ , leading to the hypothesis that transport properties may be linked more closely to extrinsic properties.
