Two new molybdenum phosphate complexes, [Cu 2 (phen) 4 (μ‐Cl)][PMo 12 O 40 ]·H 2 O (phen = 1,10‐phenanthroline) ( 1 ) and (Hbpy)[Cu I (bpy)] 2 [PMo V 2 Mo VI 10 O 39 ] (bpy = 4,4′‐bipyridine) ( 2 ), have been prepared under mild hydrothermal conditions and structurally characterized by single‐crystal X‐ray diffraction. Compounds 1 and 2 crystallize in triclinic system, space group ${\rm P}{\bar 1}$ , with a = 12.5458(7) Å, b = 13.4486(8) Å, c = 21.2406(12) Å, α = 99.7020(10)°, β = 94.2320(10)°, γ = 95.0890(10)°, V = 3504.2(3) Å 3 and Z = 2 for 1 , and a = 10.7871(6) Å, b = 10.9016(6) Å, c = 12.7897(7) Å, α = 96.8500(10)°, β = 110.0850(10)°, γ = 103.5800(10)°, V = 1339.74(13) Å 3 and Z = 1 for 2 . Compound 1 contains a [Cu 2 (phen) 4 (μ‐Cl)] 3+ cation in which two similar [Cu(phen) 2 ] units are bridged by one chlorine atom. Compound 2 contains one‐dimensional straight chain of Keggin polyoxoanions [PMo V 2 Mo VI 10 O 39 ] n 3− and two linear cationic chains of [Cu I (bpy)] n n+ . The molecular packing shows a two‐dimensional network, which is formed by the cross of the linear Keggin anions and Cu‐bpy cations.
