Structure of [(bipy)In(Cl)(SC{O}Ph) 2]

Abstract

The crystal lattice of [(bipy)In(Cl)(SC{O}Ph) 2] contains dichloromethane solvate molecules in the complex:solvent ratio 1:1. The In(III) atom is bonded to a 2,2′-bipyridine ligand, one chloride anion and two thiobenzoate anions. Of the latter, one thiobenzoate anion binds in a bidentate fashion while the other is bonded mainly through the sulfur atom with a very weakly interacting oxygen atom. The coordination geometry around In(1) can be described as highly distorted octahedral. This is inferred from the trans angles. The In(1)-N(1) and In(1)-N(2) distances are 2.348(4) and 2.285,(4) Å, respectively and this significant difference, in the In-N distances reveals that the 2,2′-bipyridine ligand is asymmetrically bonded to the In(III) centre. The In(1)-O(2) separation, 3.083(4) Å, is longer than the In(1)-O(1) distance, 2.494(3) Å, but shorter than the sum of their van der Waals radii (3.4Å) and hence could be aptly termed as very weak interaction.
