A novel molybdenum-oxide-based metal–organic hybrid compound with 3-fold interpenetrated topology

Abstract

A novel complex {[Cu 12 (4,4´-bpz) 12 (H 2 Mo 8 O 28 ) 3/2 (Mo 8 O 26 ) 3/2 ]·3(H 3 O)} n ( 1 ) has been hydrothermally synthesized from the self-assembly of CuSO 4 , H 2 MoO 4 and 4,4´-H 2 bpz [4,4´-bpz = 3,3´,5,5´-tetramethyl-substituted 4,4´-bipyrazole] and H 2 O. Its structure is composed of rare (CuL) ∞ castellated chains that are linked by two kinds of molybdenum-oxide clusters to form an unusual two dimensional 3-fold interpenetrated structure. Photoluminescent investigation reveals that the title complex displays a strong blue-light emission. A novel polyoxometalate-containing metal–organic hybrid compound with unusual 3-fold interpenetration (6.3) topology was synthesized, which is the first example included two kinds of molybdenum oxide anion clusters [Mo 8 O 26 ] 4 − and [Mo 8 O 26 (OH) 2 ] 6 − . ► A novel polyoxometalate-containing metal – organic hybrid compound with unusual 3-fold interpenetration 2-D (6.3) topology was synthesized. ► It is the first example which included two kinds of molybdenum anion clusters [Mo 8 O 26 ] 4 − and [Mo 8 O 26 (OH) 2 ] 6 − ► It exhibits two kinds of photoluminescent emission.
