Dicarbon-yl(pyrazine-1,3-dithiol-ato-?S,S')bis-(trimethyl-phosphane-?P)iron(II).

ABSTRACT: The title compound, [Fe(C(4)H(2)N(2)S(2))(C(3)H(9)P)(2)(CO)(2)], was obtained as a mononuclear by-product during the treatment of [Fe(2)(?-S(2)C(4)N(2)H(2))(CO)(6)] in excess trimethyl-phosphane. The Fe atom is six-coordinated by two thiol-ate S atoms, two phosphane P atoms and two carbonyl C atoms in a distorted octa-hedral geometry. The average Fe-C(O) distance (1.771?Å) is relatively shorter than that of its parent hexa-carbonyl-diiron compound, and differs by 0.511?Å from the average Fe-P(Me)(3) distance. The five-membered FeC(2)S(2) chelate ring plane is close to being perpendicular to the P/Fe/P plane [86.5?(2)°].

The title compound, [Fe(C(4)H(2)N(2)S(2))(C(3)H(9)P)(2)(CO)(2)], was obtained as a mononuclear by-product during the treatment of [Fe(2)(μ-S(2)C(4)N(2)H(2))(CO)(6)] in excess trimethyl-phosphane. The Fe atom is six-coordinated by two thiol-ate S atoms, two phosphane P atoms and two carbonyl C atoms in a distorted octa-hedral geometry.

μ-Propane-1,3-dithiol-ato-κS,S':S,S'-bis-[dicarbon-yl(triphenyl-phosphane-κP)iron(II)](Fe-Fe).

Project description:The title compound, [Fe(2)(C(3)H(6)S(2))(C(18)H(15)P)(2)(CO)(4)], which might serve as an active-site model of [FeFe]-hydrogenase, contains two fused Fe/S/C/C/C/S six-membered rings, one of which has a chair conformation and the other a boat conformation. Each Fe atom is coordinated by two carbonyl ligands, a triphenyl-phosphane ligand and a bis-bidentate dithiol-ate ligand, and also forms an Fe-Fe bond [2.5167 (16) Å]. Together, the six bonded atoms form a very distorted octa-hedral arrangement.

{?-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(triethyl-ammonium) bis-(μ-pyrazine-2,3-dithiol-ato)bis-(pyrazine-2,3-dithio-lato)diferrate(III) methanol disolvate.

Project description:In the title compound, (C(6)H(16)N)(2)[Fe(2)(C(4)H(2)N(2)S(2))(4)]·2CH(4)O, the [Fe(III)(pdt)(2)](-) anion (pdt is pyrazine-2,3-dithiol-ate) forms a centrosymmetric dimer supported by two Fe(III)-S bonds [Fe-S = 2.4787 (4) Å]. In the crystal structure, dimers form a one-dimensional stack along the b axis via π-π stacking inter-actions, the inter-planar separation between adjacent dimers being 3.51 (2) Å. The methanol solvent mol-ecule is involved in two hydrogen bonds in which the hydroxyl group acts as a hydrogen-bond donor to the N atom of a pdt ligand and the O atom acts as an acceptor for the NH group of the triethyl-ammonium cation.

2,5-Bis(1,3-dithiol-2-yl-idene)-1,3-dithiol-ane-4-thione.

Project description:The asymmetric unit of the title compound, C(9)H(4)S(7), contains two independent mol-ecules, in one of which the central five-membered ring is disordered over two orientations in a 0.924?(3):0.076?(3) ratio. The mol-ecular skeleton is almost planar: the average distance of the atoms from their mean plane is 0.128?(7)?Å in the ordered mol-ecule, and 0.088?(5) and 0.123?(2)?Å in the major and minor disorder components, respectively. The ordered and disordered mol-ecules form separate columns by stacking along the b axis. Adjacent columns inter-act via short S?S [3.33?(2), 3.434?(3), 3.444?(2), 3.503?(2), 3.519?(3) and 3.53?(4)?Å] and S?H [2.814?(2), 2.87?(7), 2.92?(2), 2.9269?(18), 2.93?(2), 2.94?(2), 2.939?(2), 2.967?(2) and 2.974?(1)?Å] contacts.

Penta-carbonyl-1?C,2?C-(?-pyrazine-2,3-dithiol-ato-1:2?S,S':S,S')(trimethyl-phosphane-1?P)diiron(I)(Fe-Fe).

Project description:In the title compound, [Fe(2)(C(4)H(2)N(2)S(2))(C(3)H(9)P)(CO)(5)], the Fe(2)S(2) core adopts a butterfly conformation. The PMe(3) ligand is coordinated in the basal position, roughly cis to the Fe-Fe bond. The Fe-Fe distance of 2.4970?(6)?Å is relatively short compared to those (ca 2.53?Å) found in another monosubstituted diiron compound. A rigid planar dithiol-ate bridge is featured, with an angle of 2.78?(1)° between the Fe-Fe bond and the normal to the pyrazine-2,3-dithiol-ate plane.

{1,3-Bis[(diphenyl-phosphanyl-?P)-oxy]prop-2-yl-?C}iodido(trimethyl-phosphane)cobalt(II).

Project description:The title compound, [Co(C(27)H(25)O(2)P(2))I(C(3)H(9)P)], was synthesized by the addition of 1-iodo-butane to a solution of the parent cobalt complex {1,3-bis-[(diphenyl-phosphan-yl)-oxy]prop-2-yl}bis-(trimethyl-phosphane)cobalt(II). Two five-membered cobaltocycles with considerable ring bending (sum of inter-nal angles = 516.4 and 517.7°) are formed through two P atoms of the PPh(2) groups and a metallated Csp(3) atom. The Co(II) atom is centered in a trigonal-bipyramidal configuration.

{?-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.

Dicarbon-yl(?-cyclo-penta-dien-yl)bis-(trimethyl-phosphine)molybdenum(II) trifluoro-methane-sulfonate.

Project description:In the title compound, [Mo(C(5)H(5))(CO)(2)(C(3)H(9)P)(2)]CF(3)SO(3), the cationic complex displays a classical four-legged piano-stool square-pyramidal geometry with a trans configuration of the basal ligands around the Mo atom. The cyclo-penta-dienyl (Cp) ligand occupies the apical position of the piano-stool configuration. The average Mo-P bond length of the two trans PMe(3) ligands is 2.474?(5)?Å and the Mo-Cp centroid distance is 2.003?(2)?Å.

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.
