Synthesis and structural characterization of two bond isomer copper(II) complexes via molecular modeling coupled with X-ray powder diffractometry

► First structurally characterized complex with a 1,3-thiazine sulfur link to Cu(II). ► Thiazine ring is an ambidentate moiety in TdTz ligand. ► X-ray powder diffractometry is able to discern between two bond isomer complexes.
