Crystal structure of the cis and trans polymorphs of bis[μ-2-(1,3-benzothiazol-2-yl)phenolato]-κ3 N,O:O;κ3 O:N,O-bis[fac-tricarbonylrhenium(I)]1

چکیده
The title dinuclear complex, [Re2(C13H8NOS)2(CO)6], crystallizes in two polymorphs where the 2-(1,3-benzothiazol-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 octahedrally distorted metal-coordinating units fused through -oxido bridges, leading to edge-sharing dimers. The crystal packing is governed by C—H O hydrogen-bonding interactions, forming chains parallel to the c axis in I and a three-dimensional network in II.

The Sn(IV) atom in the centrosymmetric dinculear title compound, [Sn(2)(CH(3))(2)(C(6)H(5))(2)(C(9)H(6)NO)(2)Cl(2)], shows a trans-C(2)SnNO(2)Cl distorted octa-hedral coordination [C-Sn-C = 157.83 (8)°]. The quinolin-8-olate anion chelates to the Sn atom; its O atom also binds to the inversion-related Sn atom, forming the dinuclear compound. In the crystal structure, weak inter-molecular C-H⋯Cl...

Both independent Pb(II) atoms in the title compound, [Pb(2)(C(10)H(8)NO)(2)(C(2)H(3)O(2))(2)], are chelated by acetate and substituted quinolin-8-olate anions; the O atoms of the quinolin-8-olates also bridge to confer a five-coordinate status to each metal center. The geometry approximates a distorted Ψ-fac octa-hedron in which one of the sites is occupied by a stereochemically active lone pair.

In the title polymeric complex, [Ni(C(2)H(6)NO(3)S)(2)](n), the Ni(II) ion occupies a special position on an inversion centre and displays a slightly distorted octa-hedral coordination geometry, being linked to four sulfonate O atoms and to two N atoms of the taurine ligands. The sulfonate groups doubly bridge symmetry-related Ni(II) centers, forming polymeric chains along the a axis.
