title: Crystal structure of thecisandtranspolymorphs of bis-[μ-2-(1,3-benzo-thia-zol-2-yl)phenolato]-κ3N,O:O;κ3O:N,O-bis-[fac-tri-carbonyl-rhenium(I)].
abstract: The title dinuclear complex, [Re2(C13H8NOS)2(CO)6], crystallizes in two polymorphs where the 2-(1,3-benzo-thia-zol-2-yl)phenolate ligands and two carbonyl groups aretrans- (I) orcis-arranged (II) with respect to the [Re2O2(CO)4] core. PolymorphsIandIIexhibit a crystallographically imposed centre of symmetry and a twofold rotation axis, respectively. The structures may be described as being formed by two octa-hedrally distorted metal-coordinating units fused through μ-oxido bridges, leading to edge-sharing dimers. The crystal packing is governed by C-H⋯O hydrogen-bonding inter-actions, forming chains parallel to thecaxis inIand a three-dimensional network inII.
