The crystal structures of [Tl(tsac)] ( 1 ) and [Tl(tsac)(ophen)] ( 2 ) (tsac = anion of thiosaccharin; ophen = 1, 10 phenanthroline) have been determined at 116 K by single crystal X‐ray diffractometry. Complex 1 crystallizes in the monoclinic space group P2 1 /a with Z = 4 and complex 2 in the monoclinic space group C2/c with Z = 8.In both complexes T I is coordinated to a thiosaccharinate anion through its sulphur and nitrogen atoms. A distorted eight fold coordination sphere around the cation in complex 1 is completed with two other longer Tl‐S bonds and four Tl···O contacts with five symmetry related neighbouring thiosaccharinate anions. A phenanthroline molecule acting as a bidentate ligand through its nitrogen atoms completes a four‐fold coordination around the metal atom in complex 2 . The infrared spectra of both complexes were also recorded and their most important features discussed on the basis of its structural peculiarities.
