Lower rim substituted p-tert-butyl-calix[4]arene. Part 17. Synthesis, extractive and ionophoric properties of p-tert-butylcalix[4]arene appended with hydroxamic acid moieties
The synthesis and characterization of four p-tert-butylcalix[4]arene-hydroxamic acids are reported. The dependence of the metal ion binding, assessed by liquid–liquid extraction of the metal nitrates from water into dichloromethane in individual and competitive experiments, on the ligand structure, is presented. The results showed that those ligands could be successfully used in separation proc...

The Ni(II) atom in the title compound, [Ni(C(24)H(43)P(2))(NO(3))], adopts a distorted square-planar geometry with the P atoms in a trans arrangement. The compound contains a twofold rotational axis with the nitrate group offset from this axis, except for an O atom of the nitrate group, generating two positions of 50% occupancy for the other atoms of the nitrate group.
متن کاملDichloridobis[(1S,1S′,2R,2R′)-(+)-1,1′-di-tert-butyl-2,2′-diphospholane-κ2 P,P′]ruthenium(II)
In the title compound, [RuCl(2)(C(16)H(32)P(2))(2)], the Ru(II) ion is situated on a twofold rotation axis, so the asymmetric unit contains one half-mol-ecule. The slightly distorted octa-hedral environment of the Ru center is formed by four P atoms [Ru-P = 2.4417 (6) and 2.4544 (6) Å] from two different (1S,1S',2R,2R')-TangPhos ligands [(1S,1S',2R,2R')-TangPhos = (1S,1S',2R,2R')-(+)-1,1'-di-te...
متن کامل[2,6-Bis(di-tert-butylphosphinomethyl)phenyl-κ3 P,C 1,P′](trifluoroacetato)palladium(II)
The Pd(II) atom in the title compound, [Pd(C(2)F(3)O(2))(C(24)H(43)P(2))], adopts a distorted square-planar geometry with the P atoms in a trans arrangement, forming two five-membered chelate rings. Four intra-molecular C-H⋯O hydrogen bonds occur. The crystal packing reveals one weak inter-molecular C-H⋯O hydrogen bond, which self-assembles the mol-ecules into infinite chains parallel to the b ...
متن کاملcis-{2,6-Bis[(di-tert-butylphosphanyl)methyl]cyclohexyl-κ3 P,C 1,P′}chloridopalladium(II)
The Pd(II) atom in the title compound, [Pd(C24H49P2)Cl], has a distorted square-planar CClP2 coordination geometry with the P,C,P'-tridentate ligand forming two five-membered metallacycles. The cyclo-hexane ring is aligned with the Pd(II) coordination plane due to C-H activation in an equatorial position, giving a tri-equatorial conformation of the cyclo-hexyl ring.
