Two new Y III containing sandwich‐type heterometallic tungstophosphates: [Y{PM 2 W 10 O 38 (H 2 O) 2 } 2 ] 11– (M = Co II ( 1 ) and Zn II ( 2 )) have been synthesized under mild reaction conditions. Both the molecular complexes 1 a and 2 a were synthesized by reacting Y(NO 3 ) 3 ⋅6H 2 O, M(NO 3 ) 2 ⋅6H 2 O (M = Co II and Zn II ) with Wells‐Dawson type divacant K 14 [P 2 W 19 O 69 (H 2 O)]⋅24H 2 O precursor. The potassium salts of single crystalline material were collected and further used for characterization with different analytical techniques including single crystal X‐ray diffraction (SC‐XRD), Fourier transform infrared (FT‐IR) spectroscopy, inductively coupled plasma atomic emission spectroscopy (ICP‐AES), 31 P, 183 W and 89 Y nuclear magnetic resonance (NMR) spectroscopy, high‐resolution electro‐spray ionization mass spectrometry (HR‐ESI‐MS) as well as thermogravimetric analysis. Single crystal X‐ray diffraction analysis shows that both polyanions crystallize in the orthorhombic crystal system with space group Iba2 . Each polyanion consists of ( 1,5 ) isomer of di‐metal substituted α‐Keggin type tungstophosphates, which sandwiched a Y III ion.
