A heterometallic Tb‐Pt complex, [Tb 2 Pt 3 (SAc) 12 (H 2 O) 2 ] (SAc=thioacetate), was synthesized. Dual emission was modulated by the presence of a heterometallic Tb–Pt bonding environment. The heterometallic Tb–Pt bond lowers the symmetry of the Tb ion and enhanced the emission efficiency. In addition, the Tb–Pt complex shows field‐induced multiple magnetic relaxation pathways. Furthermore, it served as an antenna for the observed dual emission. In other words, the heterometallic Tb–Pt bond has a significant effect on the luminescence and magnetic properties of the complex.
