Indium complexes thiocyanates

The indium chloride complex can be extracted from 1-4 M HCl with TO A in chloroform or 1,2-dichloroethane [8], or with n-octylaniline in CHCI3 [9]. From acidic thiocyanate media, indium has been extracted with tetra-n-hexylammonium salt in 1,2-dichloroethane [10], or with 15% TBP in kerosene [11]. Indium has been extracted also with Aliquat 3368 in xylene from 0.01 M citric acid medium [12]. 

Other Indium Compounds.— Anionic thiocyanato-complexes of In have been prepared—with Ph4As+ or (Ph3PCH2Ph)+ as cation the anion is [In(NCS)5]2 , while with Me4N+, Et3NH+, and BuJN+, [In(NCS) ] is present. Vibrational spectra are consistent with N-bonding of the ligand in each case, in agreement with earlier work on neutral adducts of In thiocyanate. ...
