Synthesis, Structure and Reactivity of Some Functionalized Zinc and Copper(II) Phosphonates

meta‐Phosphonobenzoic Acid: A Rigid Heterobifunctional Precursor for the Design of Hybrid Materials

“…It is worth noting that the influence of the condition of reactions, including the addition of basic compounds, can modify the structure of the resulting materials. [19] If the pH plays an important role in the case of the synthesis of material 5 and 6, it appears to have no influence when cobalt or manganese salts are used as inorganic precursors. Indeed, even in presence of urea ( Entry 5) are used the initial pH, respectively 1.7 and 4.4, were noticeably different, whereas the final pH was identical (6.2).…”

Open-Framework Inorganic Materials

“…This idea, initiated by Johnson and Jacobson, [229] is currently used by several groups (e.g. Zubieta in USA, [230] Bujoli [231] and Fe  rey [232,233] in France) and leads to threedimensional transition metal phosphonates with various topologies, [234] [232] using vanadium, leads to clover-like windows ( Figure 24) in which ammonium ions and water molecules lie. Such an approach, successful with the 3d transition metals, is also valuable for lanthanides.…”

A Microporous Zinc Phosphonocarboxylate with a Zeolite ABW Framework via the Trialkyl Phosphonocarboxylate Route: In situ Synthesis and Characterization of Na[Zn(O3PC2H4CO2)]·H2O

“…The accessible channel in 1 is also larger than those of the only other known metal phosphonates with the topology of zeolites i.e. Zn(O 3 PC 2 H 4 CO 2 H)·1.5H 2 O [33] and Zn(O 3 PC 2 H 4 NH 2 ) [37] in which the accessible channels also consist of 16 atoms with sizes close to those of ABW-type zeolites. Compared with ABW-type zeolites, the larger repeat unit along the hexagonal layer stacking direction and the larger channel size in 1 result from the longer connector.…”

“…This results in a structure like the (4;2) connected topology of zeolites. [38] To the best of our knowledge, only two metal phosphonates with the topology of zeolites have been reported namely Zn(O 3 PC 2 H 4 CO 2 H)·1.5H 2 O [33] and Zn(O 3 PC 2 H 4 NH 2 ). [37] Therefore, the generation of metal phosphonates with the zeolite topology poses a significant synthetic challenge due to the high coordination tendency and flexibility of organic phosphonic acids.…”
