Uranyl Diphosphonates with Pillared Structures

Inorganic Chemistry, 2009
A series of five uranyl diphosphonates with pillared and canted pillared structures have been prepared and characterized. These compounds are constructed from UO(6) tetragonal bipyramids and UO(7) pentagonal bipyramids that are bridged by the diphosphonate anions. All of these compounds fluoresce at room temperature.

Barium uranyl diphosphonates

Journal of Solid State Chemistry, 2012
Three Ba{sup 2+}/UO{sub 2}{sup 2+} methylenediphosphonates have been prepared from mild hydrothermal treatment of uranium trioxide, methylendiphosphonic acid (C1P2) with barium hydroxide octahydrate, barium iodate monohydrate, and small aliquots of HF at 200 Degree-Sign C. These compounds, Ba[UO{sub 2}[CH{sub 2}(PO{sub 3}){sub 2}]{center_dot}1.4H{sub 2}

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

DIPHOSPHONATES

The Journal of Bone and Joint Surgery. British volume, 1973
1. The phosphonates are simple chemical compounds containing P-C-P bonds which are resistant to the action of naturally occurring phosphatases and pyrophosphatases. They inhibit the formation and dissolution of apatite crystals in vitro and prevent ectopic mineralisation and bone resorption in animals. 2.

Cardiac diphosphonate uptake

Heart, 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.
