The extraction of Gadolinium (Gd) from perchlorate and nitrate media in 1,2-dichloroethane(C2H4Cl2), carbon tetrachloride (CCl4) and chloroform (CHCl3) by mixtures of 2-thenoyltrifluoroacetone (HTTA) and a crown ether benzo-15-crown-5 (B15C5) is investigated.The composition of the extracted species is determined as Gd(TTA)3.nB15C5 (n=1 in nitratemedium and n=2 in perchlorate medium). The values...

We present the synthesis and characterization of (15-crown-5)BiI3 (1) ⋅ 0.5TIE (2), a halogen bonded adduct with tetraiodoethylene (TIE), typical bond donor. Single crystal structure analysis 2 suggests bonding interaction between crown ether complex TIE. The two compounds’ thermal, optical vibrational properties are investigated in comparison, differences pointing towards notable building bloc...
