Synthesis and crystal structure from X-ray powder diffraction data of two zirconium diphosphonates containing piperazine groups.

Inorganic Chemistry, 2010
Two new zirconium aminophosphonates have been obtained by reaction of Zr(IV) with piperazine-N,N'-bis(methylenephosphonate) building blocks. Their crystal structure has been determined ab initio from X-ray powder diffraction data collected with a ...

pH-Sensitive mesoporous zirconium diphosphonates for controllable colon-targeted delivery

, 2010
pH-Sensitive mesoporous zirconium diphosphonates have been successfully synthesized through the surfactant-assisted procedure using the organophosphonate derivative of piperazine, 1,4-bis(phosphomethyl)piperazine (BPMP), and ZrCl4 as the metal precursor.

Homometallic UO2(2+) diphosphonates assembled under ambient and hydrothermal conditions.

Dalton Transactions, 2010
Four uranyl methylenediphosphonates have been synthesized from reactions of uranyl nitrate and methylenediphosphonate in water. Three of the compounds, (1) (UO(2))[CH(2)(PO(3)H)(2)](H(2)O) x 2 H(2)O, (2) (UO(2))[CH(2)(PO(3)H)(2)](H(2)O) x 4 H(2)O, and (3)

Practical enantioselective synthesis of axially chiral biaryl diphosphonates and dicarboxylates by cationic rhodium(I)/Segphos-catalyzed double [2 + 2 + 2] cycloaddition.

Organic Letters, 2008
A cationic rhodium(I)/Segphos complex catalyzes a [2 + 2 + 2] cycloaddition of internal 1,6-diynes with a phosphonate- or ester-substituted 1,3-butadiyne leading to C(2)-symmetric axially chiral biaryl diphosphonates or dicarboxylates, respectively, in ...

Further examples of the failure of surrogates to properly model the structural and hydrothermal chemistry of transuranium elements: insights provided by uranium and neptunium diphosphonates.

Inorganic Chemistry, 2008
In situ hydrothermal reduction of Np(VI) to Np(IV) in the presence of methylenediphosphonic acid (C1P2) results in the crystallization of Np[CH2(PO3)2](H2O)2 (NpC1P2-1).

Comparisons of Pu(IV) and Ce(IV) diphosphonates.

Inorganic Chemistry, 2010
The hydrothermal reaction of PuO(2) with CH(2)(PO(3)H(2))(2) results in the formation of alpha-Pu[CH(2)(PO(3))(2)](H(2)O), beta-Pu[CH(2)(PO(3))(2)](H(2)O) (1), gamma-Pu[CH(2)(PO(3))(2)](H(2)O) (2), and Pu[CH(2)(PO(3))(2)](H(2)O).H(2)O (3) as crystalline ...

The influence of two diphosphonates on calcium metabolism in the rat.

Clinical science, 1972
SUMMARY 1. The effects of two diphosphonates, disodium ethane-I-hydroxy-l,1-diphosphonate (EHDP) and disodium dichloromethylene diphosphonate (C1,MDP) on several variables of calcium metabolism have been measured in the intact rat using the model of ...

Metabolic Effects of Diphosphonate in Primary Hyperparathyroidism

The Journal of Clinical Pharmacology, 1977
Six patients with primary hyperparathyroidism (PHPT) and one with squamous cell carcinoma of the esophagus with parathyroid hormone excess received disodium ethane-1-hydroxy-1,1-diphosphonate (EHDP) at a daily dose of 20 mg/kg orally. During treatment, the decrease in urinary calcium, total urinary hydroxyproline, and fasting urinary calcium suggested ...

Synthesis, characterization, and crystal structures of two divalent metal diphosphonates with a layered and a 3D network structure.

Inorganic Chemistry, 2002
Reactions of N-methyliminobis(methylenephosphonic acid), CH(3)N(CH(2)PO(3)H(2))(2) (H(4)L), with divalent metal acetates under different conditions result in metal diphosphonates with different structures.
