{?-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)].

ABSTRACT: 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.

{?-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)].

Project description: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.

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)°].

Project description:In the title compound, C(10)H(7)NO(2)S, the dihedral angle between the benzimidazole and malonaldehyde group is 1.41?(2)°. An intra-molecular hydrogen bond is formed between the NH group and one of the adjacent carbonyl O atoms. 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.

1-(2-Fluoro-benz-yl)quinolinium bis-(2-sulfanylidene-1,3-dithiole-4,5-dithiol-ato-?S,S')nickelate(III).

Project description:The crystal structure of the title compound, (C(16)H(13)FN)[Ni(C(3)S(5))(2)], consists of Ni(III) complex anions and 1-(2-fluoro-benz-yl)quinolinium (fbq) cations. In the complex anion, the Ni(III) cation is chelated by two 2-sulfanylidene-1,3-dithiole-4,5-dithiol-ate (dmit) dianions in a distorted square-planar geometry; the two dmit mean planes are twisted with respect to each other at a dihedral angle of 8.44?(3)°. In the fbq cation, the dihedral angle between the benzene ring and the quinoline ring system is 80.57?(14)°. The centroid-centroid distance of 3.860?(5)?Å between benzene rings indicates ?-? stacking between adjacent fbq cations. The distance of 3.4958?(18)?Å between the S atom and the centroid of the pyridine ring suggests the existence of a lone-pair-aromatic inter-action between the anion and the cation. A short S?S contact [3.387?(2)?Å] is also observed in the crystal structure.
