Synthesis and crystal structure of [(Sp)-(2-phenylferrocenyl)methyl]trimethylammonium iodide dichloromethane monosolvate

ABSTRACT: The packing of the title disubstituted ferrocene derivative is stabilized by weak C—H⋯X (X = I, Cl), C—H⋯π(Cp) and C—Cl⋯π(phenyl) interactions, building a three-dimensional network. The cation has planar chirality with Sp(Fc) absolute configuration. The structure of the title compound is compared with related disubstituted (trimethylammonio)methyl ferrocenes. As a follow-up to our research on the chemistry of disubstituted ferrocene derivatives, the synthesis and the structure of the title compound, [Fe(C5H5)(C15H19N)]I·CH2Cl2, is described. The cation molecule is built up from a ferrocene disubstituted by a trimethylammonium methyl group and a phenyl ring. The asymmetric unit contains the iodide to equilibrate the charge and a disordered dichloromethane solvate. The disordered model results from a roughly statistical exchange (0.6/0.4) between one Cl and one H. The packing of the structure is stabilized by weak C—H⋯X (X = I, Cl), C—H⋯π(Cp) and C—Cl⋯π(phenyl) interactions, building a three-dimensional network. The cation has planar chirality with Sp(Fc) absolute configuration. The structure of the title compound is compared with related disubstituted (trimethylammonio)methyl ferrocenes.

rac-{[2-(Diphenyl-thio-phosphan-yl)ferrocen-yl]meth-yl}trimethyl-ammonium iodide chloro-form monosolvate.

Project description:The title compound, [Fe(C5H5)(C21H24NPS)]I·CHCl3, is built up from a (ferrocenylmeth-yl)trimethyl-ammonium cation, a iodine anion and a chloro-form solvent mol-ecule, all residing in general positions. The N atom of the ammonium group is displaced by 1.182 (2) Å from the plane of the substituted cyclo-penta-dienyl (Cp) ring towards the Fe atom, whereas the C atom attached to the same Cp ring is slightly below this plane by -0.128 (2) Å. These deviations might result from weak agostic interactions between the two H atoms of the CH2 group and the Fe atom.

Crystal structure of bis-{(<i>S</i>)-1-[2-(di-phenyl-phosphan-yl)ferrocen-yl]-(<i>R</i>)-eth-yl}ammonium bromide di-chloro-methane monosolvate.

Project description:During the synthesis of an FeBr2 complex with the PNP ligand (R,R,SFc,SFc)-[Fe2(C5H5)2(C38H35NP2)] (1), single crystals of the di-chloro-methane monosolvate of the Br- salt of the protonated ligand 1H+ were obtained serendipitously, i.e. [Fe2(C5H5)2(C38H36NP2)]Br·CH2Cl2. The crystal structure of 1H·Br·CH2Cl2 was determined by single-crystal X-ray diffraction. The mean bond lengths in the ferrocene units are Fe-C = 2.049 (3) Å and C-C = 1.422 (4) Å within the cyclo-penta-dienyl rings. The mean C-N bond length is 1.523 (4) Å. The inter-planar angle between the two connected cyclo-penta-dienyl rings is 49.2 (2)°. One ferrocene moiety adopts a staggered conformation, whereas the other is between staggered and eclipsed. The Br- ions and the CH2Cl2 mol-ecules are located in channels extending along <100>. One ammonium H atom forms a hydrogen bond with the Br- ion [H⋯Br = 2.32 (4) Å and C-H⋯Br = 172 (3)°]. The second ammonium H atom is not involved in hydrogen bonding.

Synthesis and crystal structure of tri-ethyl-ammonium hexa-bromido-uranate(IV) di-chloro-methane monosolvate.

Project description:Tri-ethyl-ammonium hexa-bromido-uranate(IV) di-chloro-methane monosolvate, [(C2H5)3NH]2[UBr6]·CH2Cl2, was obtained in the form of dark-brown crystals from the reaction of uranium penta-bromide with NEt3 and ethyl-ene glycol in di-chloro-methane at low temperature. During the progress of the reaction, the reduction of uranium(V) to uranium(IV) was observed, whose associated oxidation product could not be identified. The uranium atom of the [UBr6]2- anion is coordinated by six bromido ligands in the shape of an octa-hedron. Between cations, anion and solvent mol-ecules of crystallization, numerous C-H⋯Hal hydrogen-bond-like inter-actions are present, leading to a three-dimensional network structure.

rac-{[2-(Diphenyl-thio-phosphor-yl)ferrocen-yl]meth-yl}dimethyl-ammonium diphenyl-dithio-phosphinate.

Project description:2-(Diphenyl-thio-phosphino)dimethyl-amino-methyl-ferrocene is a key inter-mediate in the synthesis of various ferrocenyl ligands. During one such synthesis, the title compound, [Fe(C(5)H(5))(C(20)H(22)NPS)](C(12)H(10)PS(2)), was isolated as a by-product. It is built up by association of (2-(diphenyl-phosphino)ferrocen-yl)meth-yl)dimethyl-ammonium cations and diphenyl-phosphino dithio-ate anions. N-H?S, C-H?S and C-H?? inter-actions link the anions and cations. Each anion-cation pair is linked two by two through C-H?? inter-actions, forming pseudo dimers.

The dihedral angle between the two Cp rings is 3.20 (17)°. The crystal packing is mainly stabilized by van der Waals forces.

Crystal structure of {[1'-(di-phenyl-phosphino)ferrocen-yl]meth-yl}di-methyl-ammonium chloride monohydrate.

Project description:Individual ions and the solvating water mol-ecule constituting the structure of the title compound, [Fe(C8H13N)(C17H14P)]Cl·H2O, assemble into dimeric units located around crystallographic inversion centers via N-H⋯Cl and O-H⋯Cl hydrogen bonds. These discrete fragments are further inter-connected into chains by C-H⋯O inter-actions. The disubstituted ferrocene core in the {[1'-(di-phenyl-phosphino)ferrocen-yl]meth-yl}di-methyl-ammonium cation has an approximate synclinal eclipsed conformation and is tilted by 3.40 (11)°.

Bis{2-[(Tri-phenyl-meth-yl)amino]-phen-yl} diselenide aceto-nitrile monosolvate.

Project description:The mol-ecular structure of the title compound, C50H40N2Se2·C2H3N, shows a syn conformation of the benzene rings bound to the Se atoms, with an Se-Se bond length of 2.3529 (6) Å and a C-Se-Se-C torsion angle of 93.53 (14)°. The two Se-bonded aromatic ring planes make a dihedral angle of 18.42 (16)°. Intra-molecular N-H⋯Se hydrogen bonds are noted. Inter-molecular C-H⋯Se inter-actions give rise to supra-molecular chains extended along [100]. One severely disordered aceto-nitrile solvent mol-ecule per asymmetric unit was treated with SQUEEZE in PLATON [Spek (2009 ▶). Acta Cryst. D65, 148-155]; the crystal data take the presence of this mol-ecule into account.

(R)-[1-(2-Chloro-phen-yl)-2-meth-oxy-2-oxoeth-yl][2-(thio-phen-2-yl)eth-yl]ammonium (+)-camphor-10-sulfonate acetone monosolvate.

Project description:The title compound, C(15)H(17)ClNO(2)S(+)·C(10)H(15)O(4)S(-)·C(3)H(6)O, was synthesized by N-alkyl-ation of α-amino-(2-chloro-phen-yl)acetate with 2-thienylethyl p-toluene-sulfonate, followed by reaction with (+)-camphor-10-sulfonic acid. In the crystal, the cations and anions are linked through N-H⋯O hydrogen bonds. The thio-phene ring of the cation was found to be disordered over two sites, with refined occupancies of 0.798 (4) and 0.202 (4).

Pyrimethaminium 2-{[4-(tri-fluoro-meth-yl)phen-yl]sulfan-yl}benzoate dimethyl sulfoxide monosolvate.

Project description:In the cation of the title solvated mol-ecular salt, C12H14ClN4 (+)·C14H8F3O2S(-)·C2H6OS [systematic name of the cation: 2,4-di-amino-5-(4-chloro-phen-yl)-6-ethyl-pyrimidin-1-ium], the dihedral angle between the planes of the pyrimidinium and 4-chloro-phenyl rings is 77.2 (5)°. In the anion, the planes of the benzene rings are twisted with respect to each other by 71.5 (5)°. Disorder was modelled for the dimethyl sulfoxide solvent mol-ecule over two set of sites in a 0.7487 (13):0.2513 (13) ratio. In the crystal, the cations are linked by inversion-generated pairs of N-H⋯N hydrogen bonds, with an R 2 (2)(8) graph-set motif. The cation donates two N-H⋯O hydrogen bonds to the anion, also generating an R 2 (2)(8) loop. These inter-actions, along with cation-solvent N-H⋯O hydrogen bonds, and cation-anion C-H⋯F, solvent-anion C-H⋯O and C-H⋯F inter-actions, result in a three-dimensional network.

Crystal structure of zwitterionic 2-[bis-(2-meth-oxy-phen-yl)phosphanium-yl]-4-methyl-benzene-sulfonate monohydrate di-chloro-methane monosolvate.

Project description:In the title compound, C21H21O5PS·H2O·CH2Cl2, the phospho-nium-sulfonate zwitterion has the acidic H atom located on the P atom rather than the sulfonate group. The S-O bond lengths [1.4453 (15)-1.4521 (14) Å] are essentially equal. In the crystal, the water mol-ecules bridge two zwitterions via Owater-H⋯Osulfonate hydrogen bonds into a centrosymmetric dimer. The dimers are further linked by weak CAr-yl-H⋯Osulfonate hydrogen bonds into chains extending along [100]. The PH(+) group is not involved in inter-molecular inter-actions.
