CuTi2-xMxS4 (M=Fe, Mn, Co; x=0.3, 0.5) and CuCr2-xTixSe4 (x=03, 0.5, 0.7) chalcospinels were synthesized by conventional solid-state reactions. Their crystal structures were determined by single-crystal X-ray diffraction. All of the phases crystallized in cubic spinel-type structures (space group, Fd (3) over barm). For all of the chalcospinel compounds, the edge-length distortion parameter (ELD) indicated that the most distorted polyhedron was Q(Ti,M)(3)Cu, which displayed an similar to 8% distortion from an ideal tetrahedron structure (Q=S or Se)., The Mn-based thiospinel CuMn0.3Ti1.7S4 is paramagnetic, whereas the Fe-based thiospinels (CuTi2-xFexS4; x=0.3 and 0.7) are strongly antiferromagnetic due to their spin-glass states. The magnetic susceptibility measurements indicated ferromagnetic behavior for the selenospinels (CuCr2-xTixSe4; x=0.3, 0.5 and 0.7).
