{?-2-[4-(1,3-Benzothia-zol-2-yl)phen-yl]-2-aza-propane-1,3-dithiol-ato-?S,S':S,S'}bis-[tricarbonyl-iron(I)].

ABSTRACT: The title compound, [Fe(2)(C(15)H(12)N(2)S(3))(CO)(6)], was prepared as an aza-dithiol-atodiiron model for the active site of [FeFe]-hydrogenase. The Fe(2)S(2) core adopts a butterfly shape, with each metal having a pseudo square-pyramidal geometry. The N-substituted aza-dithiol-ate is ?(2)-?(4)S,S':S,S'-coordinated to the Fe(CO)(3) moieties to form two fused six-membered rings with different conformations. The sum of the C-N-C angles around the N atom [356.85?(15)°] indicates a flattening of the trigonal-pyramidal geometry about the N atom and an increase in the degree of sp(2)-hybridization.

{?-2-[4-(Benzothia-zol-2-yl)benz-yl]-2-aza-propane-1,3-dithiol-ato-1:2?S,S':S,S'}bis-[tricarbonyl-iron(I)].

Project description:The title compound, [Fe(2)(C(16)H(14)N(2)S(3))(CO)(6)], was prepared as the biomimetic model for the active site of iron-only hydrogenase. The structure is similar to the diiron subsite of the iron-only hydrogenase active site, and contains a diiron-aza-dithiol-ate moiety in which a boat six-membered ring is fused with a chair six-membered ring. The substituted benzyl group attached to the bridging N atom resides in an equatorial position. The sum of the C-N-C angles around this N atom [331.9?(12)°] indicates sp(3) hybridization.

Bis{?-[4-(1,3-benzothia-zol-2-yl)phen-yl]methane-thiol-ato-?S,S':S,S'}bis-[tricarbonyl-iron(I)](Fe-Fe).

Project description:The title compound, [Fe(2)(C(14)H(10)NS(2))(2)(CO)(6)], was synthesized as a structural and biochemical model for the active site of [FeFe]-hydrogenase. The bond lengths (Fe-Fe, Fe-S and Fe-C) and angles (C-Fe-Fe and Fe-S-Fe) are within expected ranges. The S?S distance [2.9069?(12)?Å] and the dihedral angle between two Fe-S-Fe planes [78.5?(3)°] of the butterfly-shaped Fe(2)S(2) core are enlarged compared with related bridged dithiol-ate diiron analogues. The calculated 4-benzothia-zolebenzyl best planes are almost parallel [dihedral angle = 3.7?(7)°].

2-({[4-(1,3-Benzothia-zol-2-yl)phen-yl]amino}methyl)-phenol.

Project description:In the title compound, C(20)H(16)N(2)OS, the aniline substituent essentially coplanar with the benzothia-zole moiety (with an r.m.s. deviation of all fitted non-H atoms of 0.0612?Å). The phenol group is almost perpendic-ular to the benzothia-zolylaniline group, with an inter-planar angle of 88.36?(2)°. In the crystal, mol-ecules aggregate as centrosymmetric dimers by pairs of O-H?N hydrogen bonds. C-H?O contacts and N-H??(arene) inter-actions also occur.

Project description:The mol-ecule of the title compound, C(30)H(24)N(2)O(2)S(2), adopts a transoid conformation consistent with the inversion centre located at the mid-point of the central C-C single bond, resulting in one half mol-ecule in the asymmetric unit. The dihedral angle between the coplanar benzothia-zole ring system and the benzene ring is 11.06 (7)°. In the crystal structure, mol-ecules are linked by weak inter-molecular π-π inter-actions between thia-zole and benzene rings to form a three-dimensional network.

In addition, the NH group forms an inter-molecular hydrogen bond to a symmetry equivalent of this carbonyl O atom, connecting the mol-ecules into centrosymmetric dimers. The structure also contains C-H?O inter-molecular inter-actions.

N-[(E)-Thio-phen-2-yl-methyl-idene]-1,3-benzothia-zol-2-amine.

Project description:In the title thio-phene-derived Schiff base compound, C(12)H(8)N(2)S(2), the thio-phene ring is slighty rotated from the benzothia-zole group mean plane, giving a dihedral angle of 12.87 (6)°. The largest displacement of an atom in the mol-ecule from the nine-atom mean plane defined by the non-H atoms of the benzothia-zole ring system is 0.572 (1) Å, exhibited by the C atom at the 3-position of the thio-phene ring. In the crystal, weak C-H⋯S hydrogen bonds involving the thio-phene group S atom and the 4-position thio-phene C-H group of a symmetry-related mol-ecule lead to an infinite one-dimensional chain colinear with the c axis. The structure is further stabilized by π-π inter-actions; the distance between the thia-zole ring centroid and the centroid of an adjacent benzene ring is 3.686 (1) Å. The crystal studied was an inversion twin with the ratio of components 0.73 (3):0.27 (3).
