of pentaand hexavalentactinides with phosphoryl-containing podands incorporating a triethylene glycol fragment and 2-(diphenylphosphinyl)phenyl (L1) or 2-(diphenylphosphinylmethyl)phenyl (L) end groups were synthesized and structurally characterized. The complexes can be described by the following formulas: [NpO2L(C2H5OH)(NO3)] (I) for pentavalent neptunium and [AnO2(L1)2](OH)2 · nH2O (II), where An
合成了五价和六价act系元素与掺有三甘醇片段和2-(二苯基膦基)苯基(L 1)或2-(二苯基膦基甲基)苯基(L)端基的含磷的Podand的配合物,并对其结构进行了表征。配合物可以用下式描述:[NpO 2 L(C 2 H 5 OH)(NO 3)](I)五价n和[AnO 2(L 1)2 ](OH)2 · n H 2 O(II),其中An是U(IIa),Np(IIb)和Pu(IIc),用于六价act系元素的同构化合物。在I中,L是双齿桥联配体。Np 5+配位多面体为五边形双锥体。双金字塔赤道平面由两个豆荚L的氧原子,二齿硝酸根离子和乙醇OH基形成。荚果的磷酰基的氧原子参与两个NpO + 2阳离子的配位环境,在该环境中,它们将电中性的硝酸壬基硝酸酯片段沿[100]方向连接到无限链,而这些链又通过强力连接成带氢键。II的晶体由络合物阳离子[AnO 2(L 1) 2 ] 2+,氢氧根离子和水分子结晶。AnO

oxide terminalgroups have been synthesised. Stability constants, enthalpies and entropies of their complexation with lithium, sodium and potassium thiocyanates have been determined in acetonitrile at 298 K by a calorimetric titration technique. We find that tri-podands form a variety of complexes [(M+)3L, (M+)2L, M+L and M+L2)], whereas the bi- and mono-podand form only M+L complexes with Li+ and Na+

method for preparing phosphoryl podand 1,8-bis[2-(diphenylphosphorylmethyl)phenoxy]-3,6-dioxaoctane (L) has been developed. Recovery of Pb2+ with impregnated type sorbents was studied, the sorbents contain isodentate organic ligands—phosphoryl podand L and crown ether (4,4',(5')-di(tert-butyl)dicyclohexyl-18-crown-6)—as extractants. A sorbent based on the phosphoryl podand quantitatively extracts lead
