Copper–Fluorenephosphonate Cu­(PO₃‐C₁₃H₉)·H₂O: A Layered Antiferromagnetic Hybrid

Abstract

A Cu(PO 3 -C 13 H 9 )·H 2 O hybrid compound has been synthesized by a hydrothermal method from Cu(NO 3 ) 2 ·3H 2 O and 9H-fluorene-2-phosphonic acid [C 13 H 9 PO(OH) 2 ]. Its structure was determined by X-ray diffraction performed on a single crystal. The compound crystallizes in the monoclinic centrosymmetric space group P2 1 /a [a = 7.4977 (5)

The Dimeric Pyramidal Cu2O6(H2O)2 Unit – A Structural Invariant of a Homologous Series of Copper‐Layered Phosphonates

“…7.5 × 7.5 Å. In the single phosphonates Cu(H 2 O)PO 3 R, this arrangement of the inorganic layers is indeed observed for a large variety of organic groups, namely, 3‐fluorophenyl (present work), 5‐(2‐bromothienyl), methyl,, ethyl, propyl, bromoethyl, benzyl, 2‐carboxyethyl, cyclohexene, and fluorene . The number of [Cu 2 (H 2 O) 2 (O 3 P–R–PO 3 )] diphosphonates is quite limited; in addition to the thiophenyl phase R = C 4 H 2 S obtained in the present work, only two copper diphosphonates corresponding to this generic formulation with the same arrangement of the inorganic layers have been synthesized previously for R = C 2 H 4 , and p ‐C 6 H 4 …”

Designing of a Magnetodielectric System in Hybrid Organic–Inorganic Framework, a Perovskite Layered Phosphonate MnO3PC6H4‐m‐Br⋅H2O

“…Aromatic phosphonic acids can be prepared by a series of methods but one of the most convenient consists in a phosphonation of bromoaryl derivatives according to the Tavs's method or a modified version of this catalytic assisted Arbuzov reaction . This procedure is usually very efficient for the preparation of mono or poly arylphosphonates . Then, the hydrolysis of phosphonate to phosphonic acid can be achieved in acidic condition .…”

M(H2O)(PO3C10H6OH)·(H2O)0.5 (M = Co, Mn, Zn, Cu): a new series of layered metallophosphonate compounds obtained from 6-hydroxy-2-naphthylphosphonic acid

“…17 The functionalization of the organic moieties allowed the introduction of new properties including coordination properties used for catalysis 18,19 and asymmetric catalysis, 20 ionic conduction, 21 and fluorescence 22 or the preparation of microporous 23 or mesoporous 24 materials. On the other hand, a rational selection of the metal ions offered properties like magnetism, 25,26 luminescence, [27][28][29] bactericidal action 30 or controlled metallic salt release. 31 In our laboratories, we developed a strategy that consisted of preparing rigid phosphonic acids 32 possessing a low symmetry 33 with the aim of synthesiz-ing non-centrosymmetric metal-phosphonate hybrids as a prerequisite for producing materials featuring multiferroic properties.…”
