A substructural molecular fragment (SMF) method has been developed to model the relationships between the structure of organic molecules and their thermodynamic parameters of complexation or extraction. The method is based on the splitting of a molecule into fragments, and on calculations of their contributions to a given property. It uses two types of fragments: atom/bond sequences and "augmented atoms" (atoms with their nearest neighbors). The SMF approach is tested on physical properties of C2-C9 alkanes (boiling point, molar volume, molar refraction, heat of vaporization, surface tension, melting point, critical temperature, and critical pressures) and on octanol/water partition coefficients. Then, it is applied to the assessment of (i) complexation stability constants of alkali cations with crown ethers and phosphoryl-containing podands, and of beta-cyclodextrins with mono- and 1,4-disubstituted benzenes, and (ii) solvent extraction constants for the complexes of uranyl cation by phosphoryl-containing ligands.

The structural properties of copper complexes with (2-hydroxyphenyl)di-p-tolylphosphane oxide (CuL 1 2 ) and 3-(2-hy-2 ) are studied in detail. The o-phosphorylated phenols demonstrate both bridging and chelating behaviour, and the main reaction product is a coordination polymer containing dimeric Cu 2 O 8 fragments. The structural peculiarities of the o-phosphorylated phenols were revealed by single-crystal X-ray diffraction. The copper complexes are [a]

“…The logarithms of the stability constants measured under the same conditions for the the lithium complexes of phosphoryl podand L (log K 7.0) and its close structural analogue L 1 (log K 6.7) are higher than those for the known crown ethers (12C4, 15C5, 18C6, B18C6, and DB18C6) [4,5].…”

“…However, only few complexing organic compounds for the effective binding of lithium cation are known. As a rule, they are crown ethers with the cavity of small radius [3] and phosphoryl podands; among the latter the most interesting are oligoethylene glycol diphenyl ethers ortho-substituted with diphenylphosphoryl I [4] or diphenylphosphorylmethyl groups II [5] (Scheme 1).…”

Modified methods to synthesize, 1,8-bis[2-diphenylphosphoryl)phenoxy]-3,6-dioxaoctane phosphoryl podand (L), an effective complexing agent for the lithium cation, is reported. The possibility to use the phase-transfer catalysis and microwave irradiation is shown. The crystal structure of coordination complex [LiL]ClO 4 ·2C 6 H 6 is determined by X-ray diffraction analysis.Lithium compounds are used as components of compact energy sources [1]; metal lithium is used as a coolant in nuclear reactors, and isotope 6 Li is the only industrial source of tritium which is necessary for thermonuclear energetics. Lithium salts are used in psychiatry for reductive therapy of manic states and prevention of bipolar affective (manic-depressive) disorders [2]. Organic coordination compounds which are able to effectively and selectively bind the Li + cation are used for its analytical determination in technological and biological solutions and for practical recovery and purification of lithium salts from industrial solutions. However, only few complexing organic compounds for the effective binding of lithium cation are known. As a rule, they are crown ethers with the cavity of small radius [3] and phosphoryl podands; among the latter the most interesting are oligoethylene glycol diphenyl ethers ortho-substituted with diphenylphosphoryl I [4] or diphenylphosphorylmethyl groups II [5] (Scheme 1).The plot of stability constant logarithms of M + L complexes of phosphoryl podand I and II with lithium 2,4-dinitrophenolate (log K Li+ ) in THF-chloroform
