Diphosphates and diphosphonates in polyoxometalate chemistry

Chemical Society Reviews, 2012
In the wide area of polyoxometalate (POM) chemistry, diphosphate/diphosphonate-based POMs represent a more recent area of study. However, in this short time it has emerged to become very dynamic, as shown by the wide variety of compounds reported. Ever since the discovery of the first polyoxotungstate framework constructed from diphosph(on)ate ligands,

Cardiac diphosphonate uptake [PDF]

open access: possibleHeart, 2014
An elderly patient was known with generalised osteoarthritis and destruction of the right hip. Six months before, this patient was admitted to a general hospital because of oedema and ventricular tachycardia. No coronary artery disease was found on coronary angiogram and the tachycardia was successfully converted to sinus rhythm.

Zinc-diphosphonates with extended dipyridine units: synthesis, structures, in situ reactions, and photochromism.

Dalton Transactions, 2019
Two zinc-diphosphonates formed from extended dipyridine units di-3,6-(4'-pyridyl)-1,2,4,5-tetrazine (dipytz) and 1,4-di(pyridine-4-yl)benzene (pbyb), [H2-Hdpt][Zn3(HEDP)2(H2O)]·2H2O (1) and [Zn2(HEDP)(pbyb)0.5(H2O)]·H2O (2) were solvothermally prepared ...

Two-dimensional layered lanthanide diphosphonates: synthesis, structures and sensing properties toward Fe3+ and Cr2O72.

Dalton Transactions, 2019
A series of lanthanide diphosphonates, namely Ln(HL)(H2O)2 (Ln = Nd 1, Eu 2, Tb 3 and Er 4), have been synthesized from a semirigid diphosphonate ligand, (5-methyl-1,3-phenylene)bis(methylene)bisphosphonic acid (H4L). These lanthanide diphosphonates have

Syntheses and characterization of phosphonates and diphosphonates of molybdenum, A4[(MoO3)5(O3PR)2]·xH2O, A2[Mo2O5(O3PR)2] and A2[Mo2O5(O3P-R-PO3)] (A = K, Rb, Cs, Tl, NH4).

Dalton Transactions, 2017
Twenty new molybdenum phosphonates and diphosphonates have been synthesized and structurally characterized by single crystal and powder X-ray diffraction, CHN analyses, spectroscopic and thermal studies.

Two Cobalt-diphosphonates Templated by Long-Chain Flexible Amines: Synthesis, Structures, Proton Conductivity, and Magnetic Properties

, 2018
Two new cobalt-diphosphonates templated by protonated 1,2-bis(3-aminopropylamino)ethane (BAPEN), (C8N4H26)0.5·[Co(HEDP)]·H2O (1) and (C8N4H26)·[Co2(HEDP)2(H2O)2]·5H2O (2), were hydrothermally prepared (HEDP = CH3C(OH)(PO3)2, 1 ...

Incorporation of Cu(2+) ions into nanotubular uranyl diphosphonates.

Inorganic Chemistry, 2014
Three new multidimensional polymetallic uranyl diphosphonates were crystallized under mild hydrothermal conditions: [Cu(H2O)]2{(UO2)4F2[(PO3C6H4)(C6H4PO3H)3]2(bipym)}·6H2O (1), [Cu(H2O)]2{(UO2)4[(C6H4PO3)(C6H4PO3H)]4(bipym)} (2), and Cu{(UO2)(C6H4PO3)2 ...

Three new silver uranyl diphosphonates: structures and properties.

Inorganic Chemistry, 2014
The hydrothermal reaction of uranium trioxide and methylenediphosphonic acid in the presence of silver nitrate resulted in the formation of three new uranyl coordination polymers: AgUO2[CH2(PO3)(PO3H)] (Ag-1), [Ag2(H2O)1.5]{(UO2)2[CH2(PO3)2]F2}·(H2O)0.5 (

From 1D chain to 3D framework uranyl diphosphonates: syntheses, crystal structures, and selective ion exchange.

Inorganic Chemistry, 2012
In this work, we demonstrate a family of new inorganic-organic hybrid uranyl diphosphonates based on 1-hydroxyethylidenediphosphonic acid (H(4)L) linker by using hydrothermal method. These compounds, (Hbpi)[(UO(2))(H(2)O)(HL)]·H(2)O (UP-1), represents 1D
