Bis{μ-(E)-methyl 4-[(2-carbamothio-ylhydrazinyl-idene)meth-yl]benzoate-κS:S}bis-[iodido(triphenyl-phosphane-κP)copper(I)].

ABSTRACT: The title complex, [Cu(2)I(2)(C(10)H(11)N(3)O(2)S)(2)(C(18)H(15)P)(2)], is a centrosymmetric sulfur-bridged dimer of Cu(I) with PPh(3) and iodine. The Cu(I) atom shows a distorted tetra-hedral geometry, with bite angles ranging from 98.61 (2) to 120.16 (3)°. The intra-molecular Cu⋯Cu distance is 2.8228 (12) Å. The thio-semicarbazone ligand is coordinated only through the S atom. In the crystal, the complex mol-ecules are linked via inter-molecular N-H⋯O hydrogen bonds, resulting in a hydrogen-bonded chain along the b axis.

Iodido[1-(propan-2-yl-idene)thio-semi-carbazide-κS]bis-(triphenyl-phosphane-κP)copper(I).

Project description:In the mononuclear title complex, [CuI(C(4)H(9)N(3)S)(C(18)H(15)P)(2)], the Cu(I) ion displays a distorted tetra-hedral coordination geometry involving two P atoms of two triphenyl-phosphane mol-ecules, one S atom of a 1-(propan-2-yl-idene)thio-semicarbazide mol-ecule and one iodide ion. In the crystal, C-H⋯π inter-actions [C-H⋯centroid distances = 3.443 (3) and 3.788 (3) Å] and N-H⋯S hydrogen bonds form layers parallel to (100). An intra-molecular N-H⋯I hydrogen bond is also observed.

Bis(methyl xanthato)-κS;κS:S'-(triphenyl-phosphane-κP)palladium(II).

Project description:The title compound, [Pd(C(2)H(3)OS(2))(2)(C(18)H(15)P)], features a palladium complex with a triphenyl-phosphane ligand and two xanthate ligands, one of them coordinates in a bidentate and the other in a monodentate fashion, giving rise to a slightly distorted square-planar coordination of the Pd(II) ion. As a result of this difference in the coordination modes, the C-S bond lengths are different, viz. 1.687 (2) and 1.692 (2) Å in the bidentate ligand and 1.723 (2) Å in the monodentate ligand, whereas the non-coordinating S atom has a C-S distance of 1.649 (2) Å. The crystal packing is stabilized by C-H⋯O inter-actions.

trans-Iodido(pyrazinyl-κC(2))bis-(triphenyl-phosphane-κP)palladium(II).

Project description:There are two independent mol-ecules with similar configurations in the asymmetric unit of the title complex, [Pd(C(4)H(3)N(2))I(C(18)H(15)P)(2)]. In each mol-ecule, the geometry around the Pd atom is distorted square-planar, with the Pd atom displaced by 0.0549 (12) and 0.0734 (13) Å from the least-squares plane of the I-P-P-C atoms. The PPh(3) ligands are in trans positions, with P-Pd-P angles of 173.12 (4) and 170.29 (4)°, while the pyrazinyl ligands and I atoms, also trans to each other, form C-Pd-I angles of 179.38 (12) and 178.44 (12)°. In the crystal, C-H⋯π inter-actions occur, resulting in a three-dimensional supramolecular architecture.

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.

catena-Poly[[[(triphenyl-phosphane)copper(I)]-di-μ-iodido-[(triphenyl-phosphane)copper(I)]-μ-[3,6-bis-(4-pyrid-yl)-1,2,4,5-tetra-zine]] acetonitrile disolvate].

Project description:The title compound, {[Cu(2)I(2)(C(12)H(8)N(6))(C(18)H(15)P)(2)]·2CH(3)CN}(n), contains centrosymmetric dinuclear Cu(2)I(2)(PPh(3))(2) units bridged by 3,6-bis-(4-pyrid-yl)-1,2,4,5-tetra-zine ligands lying also across crystallographic inversion centers, giving a chain structure in the ab plane. The distorted tetra-hedral Cu(I) atoms in the dinuclear unit are coordinated by two bridging iodide anions, one pyridine N atom from the substituted tetra-zine ligand and one terminal triphenyl-phosphine P-atom donor. The Cu⋯Cu distance is 2.8293 (12) Å, implying a weak Cu⋯Cu inter-action.

catena-Poly[[(triphenyl-phosphane)copper(I)]-di-?-iodido-[(triphenyl-phosphane)copper(I)]-?-{1,2-bis-[1-(pyridin-4-yl)ethyl-idene]hydrazine}].

Project description:In the title coordination polymer, [Cu(2)I(2)(C(14)H(14)N(4))(C(18)H(15)P)(2)](n), the Cu(I) atom is coordinated by two I atoms, one P atom and one N atom in a fairly regular tetra-hedral arrangement. A crystallographic inversion centre generates a Cu(2)I(2) diamond with a Cu-Cu separation of 3.0120?(5)?Å. The complete N,N'-(1-pyridin-4-yl-ethethyl-idene)-hydrazine mol-ecule is also generated by inversion symmetry, and this bridging ligand leads to [011] polymeric chains in the crystal structure.

μ-2,2'-Bipyrimidine-κ(4)N(1),N(1'):N(3),N(3')-bis-[iodido(triphenyl-phosphane-κP)copper(I)] dimethyl-formamide disolvate.

Project description:In the title binuclear centrosymmetric complex, [Cu(2)I(2)(C(8)H(6)N(4))(C(18)H(15)P)(2)]·2C(3)H(7)NO, the bis-bidentate 2,2'-bipyrimidine ligand bridges two copper(I) ions, each additionally bound to an iodide anion and a triphenyl-phosphane ligand in a distorted tetra-hedral N(2)IP geometry. The complex mol-ecules pack in columns parallel to [100] generating cavities occupied by dimethyl-formamide solvent mol-ecules. Weak C-H⋯I hydrogen-bonding inter-actions help to stabilize the crystal packing.

[4-Bromo-N-(pyridin-2-yl-methyl-idene)aniline-κ(2)N,N']iodido(triphenyl-phosphane-κP)copper(I).

Project description:In the title compound, [CuI(C(12)H(9)BrN(2))(C(18)H(15)P)], the Cu(I) ion is bonded to one I atom, one triphenyl-phosphane P atom and two N atoms of the diimine ligand in a distorted tetra-hedral geometry. The Schiff base acts as a chelating ligand and coordinates to the Cu(I) atom via two N atoms. In the diimine ligand, the dihedral angle between the pyridine and bromo-phenyl rings is 19.2 (2)°. In the crystal, mol-ecules are connected by π-π stacking inter-actions between inversion-related pyridine rings [centroid-centroid distance = 3.404 (3) Å].

(Ferrocenyl-thio-phospho-nato-κS)(triphenyl-phosphane-κP)gold(I) dichloro-methane monosolvate.

Project description:In the title compound, [AuFe(C(5)H(5))(C(5)H(5)O(2)PS)(C(18)H(15)P)]·CH(2)Cl(2), the two-coordinate gold(I) atom shows a slightly distorted linear arrangement, with a P-Au-S bond angle of 176.81 (6)°. The difference in P=O and P-O(H) bond lengths, which are 1.503 (6) and 1.541 (5) Å, respectively, implies there is apparently no delocalization between the P-O bonds, and the proton appears to be localized on one O atom only. In the crystal structure, inter-molecular O-H⋯O hydrogen bonds link dinuclear mol-ecules into chains propagated in the [010] direction. The dichloro-methane solvent mol-ecule was disordered between two positions in a 0.63 (3):0.37 (3) ratio.

Di-μ-thio-semicarbazide-κ(4)S:S-bis-[chlori-dobis(triphenyl-phosphane-κP)silver(I)].

Project description:The dinuclear title complex, [Ag(2)Cl(2)(CH(5)N(3)S)(2)(C(18)H(15)P)(2)], lies across an inversion center. The Ag(I) ion exhibits a slightly distorted tetra-hedral coordination geometry formed by a P atom from a triphenyl-phosphane ligand, two metal-bridging S atoms from thio-semicabazide ligands and one chloride ion. The S atoms bridge two symmetry-related Ag(I) ions, forming a strictly planar Ag(2)S(2) core with an Ag⋯Ag separation of 2.7802 (7) Å. There is an intra-molecular N-H⋯Cl hydrogen bond. In the crystal, N-H⋯Cl and N-H⋯S hydrogen bonds link complex mol-ecules, forming layers parallel to (001). These layers are connected through π-π stacking inter-actions [centroid-centroid distance = 3.665 (2) Å], leading to the formation of a three-dimensional network.
