RESUMEN
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 are trans- (I) or cis-arranged (II) with respect to the [Re2O2(CO)4] core. Polymorphs I and II exhibit 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-Hâ¯O hydrogen-bonding inter-actions, forming chains parallel to the c axis in I and a three-dimensional network in II.
