Abstract
Crystallization of the product of the reaction between impure samples of In(NCS) 3 , prepared from InCl 3 and KSCN, and 2,2'-bipyridyl (bipy) in tetrahydrofuran solution gave the complex pentakis(tetrahydrofuran)potassium (2,2'-bipyridyl)tetrakis(isothiocyanato)indate(III), [K(C 4 H 8 O) 5 ][In(NCS) 4 (C 10 H 8 N 2 )], composed of a potassium cation coordinated by five thf ligands and one S atom of a thiocyanate group, and an octahedral indium-centred anion in which the bipy N atoms are cis and the four thiocyanates are bonded to indium through their N atoms. Crystallization of samples of impure In(NCS) 3 from pyridine in the presence of 18-crown-6 gave the compound (1,4,7,10,13,16-hexaoxacyclooctadecane)potassium bis(pyridine)tetrakis(isothiocyanato)indate(III) pyridine solvate, [K(C 12 H 24 O 6 )][In(NCS) 4 (C 5 H 5 N) 2 ].2C 5 H 5 N, containing an octahedral indium-centred anion in which the pyridine ligands are trans. The potassium in both complexes arises from the contamination of In(NCS) 3 by the KSCN used in its preparation.
