An arched dicadmium‐substituted vanadogermanate dimer, {[Cd(en) 2 ][Cd(en)] 2 Ge 8 V 12 O 40 (OH) 8 } 2 {[Cd(en)(H 2 O)] 2 } · en · 2H 2 O ( 1 ; en = ethylenediamine), was prepared hydrothermally and characterized by IR spectroscopy, elemental analysis, powder X‐ray diffraction, thermogravimetric analysis, UV/Vis diffuse reflectance spectroscopy, electrochemistry, and X‐ray single‐crystal diffraction. Notably, 1 represents the first vanadogermanate‐based dimer and contains two dicadmium‐substituted {[Cd(en) 2 ][Cd(en)] 2 Ge 8 V 12 O 40 (OH) 8 } cluster units and rare dinuclear {[Cd(en)(H 2 O)] 2+ } 2 cations as linkages. Then, the adjacent dimers are further extended by a pair of bridging [Cd(en) 2 ] 2+ complexes to form a 1D hybrid sinusoidal chain. All V ions are present in the valence of +4. The magnetic behavior demonstrates the antiferromagnetic interactions within the V IV centers. Furthermore, luminescence measurements demonstrate an intense blue luminescent emission in the solid state.
