A new zincoborophosphate templated by diethylenetriamine (DETA): Synthesis and characterizations of (C4N3H16)[Zn3B3P6O24]·H2O

Abstract

The title zincoborophosphate was synthesized hydrothermally from a mixture of ZnO, B2O3, H3PO4 and the structure-directing amine, DETA. Its crystal structure contains helices made up of corner-sharing BO4 and PO4 tetrahedra, which interconnected with ZnO4 tetrahedra to form a three dimensional structure with the CZP topology. The amine and water molecules occupy the free thread of the helices and the center of the channels, respectively. Thermal stability investigations show that this new compound can be dehydrated at 423 K and the product is stable up to 723 K. Furthermore, the as-synthesized title compound and its dehydration product are luminescent, each with a similar broad band between 350 and 550 nm, but the emission of the latter is about three times more intense than that of the former.

Open-Framework Manganese(II) and Cobalt(II) Borophosphates with Helical Chains: Structures, Magnetic, and Luminescent Properties

“…For MeBPOs (metal–BPO systems), the following representatives have been reported: M I M II (H 2 O) 2 [BP 2 O 8 ]· y H 2 O, with M I = Li, Na, K, Rb, Cs, and NH 4 , M II = Mg, Sc, Mn, Fe, Co, Ni, Cu, Zn, and Cd, and y = 0.2–1 for mono- and divalent cations, ,− and M III (H 2 O) 2 [BP 2 O 8 ]·H 2 O, with M III = Fe and In, for triply charged cations featuring a complex [BP 2 O 8 3– ] unit as the vertex-sharing BO 4 and two PO 4 tetrahedra (Figure S1). The connection of these units to extended chains results in the formation of helices that are either left- or right-handed.…”

“…The helices can be considerably compressed or expanded depending on the different sizes and charges of embedded cations. An example for the tremendous structural flexibility of this structure type is [C 4 N 3 H 16 ]­[Zn 3 B 3 P 6 O 24 ]·H 2 O, which contains large organic cations, forcing a stretch of the chains . Another interesting representative is (NH 4 ) 0.75 Fe­(H 2 O) 2 [BP 2 O 8 ]·0.25H 2 O, which contains both Fe 2+ and Fe 3+ and has been discussed as a cathode material for sodium-ion batteries .…”
