A novel phosphovanadate layered structure intercalated by 4,4′‐bipyridinium cations, (C 10 H 10 N 2 )[(VO 2 ) 4 (PO 4 ) 2 ], was synthesised under hydrothermal conditions and its crystal structure determined using single‐crystal X‐ray diffraction. The anionic [(VO 2 ) 4 (PO 4 ) 2 ] n 2n− perforated layers are strongly hydrogen bonded to the interlayer 4,4′‐bipyridinium cations and are assembled by an unprecedented secondary tetrametallic V V building unit constructed from a distorted cubane‐like {V 4 O 4 } cluster. The compound was further characterised by IR, Raman, 1 H, 1 H‐ 13 C, 31 P and 51 V MAS NMR spectroscopy, and by thermal and elemental analysis. (© Wiley‐VCH Verlag GmbH & Co.
