Hydrothermal synthesis, structure and properties of two new phosphomolybdates based on Strandberg-type {P 2 Mo 5 O 23 } 6 − building units

Abstract Two inorganic–organic hybrid compounds based on Strandberg-type phosphomolybdates (abbreviated as {P 2 Mo 5 O 23 } 6 − ) complexes [H 3 O] 2 [Cu 2 (Pyim) 2 (H 2 O) 3 ][P 2 Mo 5 O 23 ] · 6H 2 O (1) and [Cu 3 (Pyim) 3 (H 2 O) 4 ][P 2 Mo 5 O 23 ] · 7H 2 O (2) were successfully synthesized at different pH values under hydrothermal conditions. Both 1 and 2 are based on the {P 2 Mo 5 O 23 } 6 − clusters connected by copper complexes to generate one dimensional chain. The magnetic analyses of compounds 1 and 2 indicate antiferromagnetic interactions between copper ions.
