Hydrothermal synthesis and structure of a two-dimensional bimetallic copper-molybdophosphonate, [{Cu4(H2O)2(phenbisterpy)2(HO3P(CH2)4PO3H)}(Mo4FO12)2{O3P(CH2)4PO3}]·4H2O, constructed from {Mo4FO12}1− clusters and copper-ligand chains (phenbisterpy =Â

The hydrothermal reaction of Cu(CH3CO2)2·H2O, MoO3, 1,4-bis(2,2′:6′,2″-terpyridin-4′-yl)benzene (phenbisterpy), 1,4-butylenediphosphonic acid and HF yields the two-dimensional bimetallic oxyfluoride material [{Cu4(H2O)2(phenbisterpy)2(HO3P(CH2)4PO3H)}(Mo4FO12)2{O3P(CH2)4PO3}]·4H2O (1·4H2O), shown below.
