Bis(?2-di-phenyl-phosphinamide-?(2) O:O)bis-[bis(di-phenyl-phosphinamide-?O)lithium] dichloride aceto-nitrile disolvate.

ABSTRACT: The asymmetric unit of the title compound, [Li2(C12H12NOP)6]Cl2·2CH3CN, contains one-half of the centrosymmetric dication, one chloride anion and one aceto-nitrile solvent mol-ecule. Each Li atom is coordinated by four O atoms [Li-O 1.891?(3) and 2.025?(3)?Å] from the four di-phenyl-phosphinamide ligands in a distorted tetra-hedral geometry. In the crystal, weak N-H?Cl hydrogen bonds link the anions and dications into columns extending along [100].

Crystal structure of (μ-N-allyl-thio-urea-κ(2) S:S)bis-[μ-bis-(di-phenyl-phosphanyl)methane-κ(2) P:P']bis-[bromido-copper(I)] aceto-nitrile disolvate.

Project description:The reaction of cuprous bromide with a mixture of 1,1-bis-(di-phenyl-phosphan-yl)methane (dppm: C25H22P2) and N-allyl-thio-urea (ATU: C4H8N2S) in aceto-nitrile yielded the title solvated dinuclear complex, [Cu2Br2(C4H8N2S)(C25H22P2)2]·2C2H3N or [Cu2Br2(ATU)(dppm)2]·2CH3CN. Both Cu(+) ions adopt distorted tetra-hedral geometries, being coordinated by one terminal Br atom, one μ(2)-S atom of the bridging ATU ligand and two P atoms of the bridging dppm ligands. Within the complex, intra-molecular C-H⋯S, C-H⋯π, N-H⋯Br and π-π stacking inter-actions are observed. In the crystal, the components are linked by N-H⋯Br and C-H⋯N hydrogen bonds and weak π-π stacking inter-actions, generating chains propagating in the [100] direction.

2,2'-[1,2-Phenyl-enebis(aza-nedi-yl)]di-aceto-nitrile.

Project description:The title compound, C10H10N4, shows chemical but not crystallographic C2 symmetry. The two cyano-methyl groups are located in an anti position with respect to the aromatic ring. In the crystal, mol-ecules form parallel ladder-like tapes linked through two N-H?N hydrogen bonds. Further weak intra-molecular N-H?N hydrogen bonding is responsible for the elongation of one of the Caromatic-N bonds.

Crystal structure of di-?-iodido-bis-[bis(aceto-nitrile-?N)copper(I)].

Project description:The title compound, [Cu2I2(CH3CN)4], exhibits a centrosymmetric Cu2I2 core [Cu?Cu distance = 2.7482?(11)?Å], the Cu(I) atoms of which are further coordinated by four mol-ecules of aceto-nitrile. The Cu(I) atom has an overall distorted tetra-hedral coordination environment evidenced by L-Cu-L angles (L = N or I) ranging from 100.47?(10) to 117.06?(2)°. The coordination geometries of the aceto-nitrile ligands deviate slightly from linearity as shown by Cu-N-C angles of 167.0?(2) and 172.7?(2)°. In the crystal, there are no significant hydrogen-bonding inter-actions present, so the crystal packing seems to be formed predominantly by van der Waals forces.

Bis[?-1-(3,5-di-chloro-pyridin-2-yl)-2-(pyridin-3-yl-methyl-idene)hydrazine]bis-[(nitrato-?O)silver(I)] aceto-nitrile disolvate.

Project description:In the centrosymmetric binuclear title complex, [Ag2(NO3)2(C11H8Cl2N4)2]·2CH3CN, the Ag(I) atom is four-coordinated and exhibits a highly distorted tetrahedral coordination sphere defined by three N atoms from two 1-(3,5-di-chloro-pyridin-2-yl)-2-(pyridin-3-yl-methyl-idene)hy-drazine ligands and one O atom from a nitrate anion. Inter-molecular N-H?O hydrogen bonds link the complex mol-ecules, resulting in a two-dimensional supra-molecular structure parallel to (001).

Crystal structure of cis-anti-cis-di-cyclo-hexane-18-crown-6 aceto-nitrile disolvate.

Project description:The title compound (systematic name: cis-anti-cis-2,5,8,15,18,21-hexa-oxatri-cyclo-[20.4.0.0(9,14)]hexa-cosane aceto-nitrile disolvate), C20H36O6·2CH3CN, crystallizes from an aceto-nitrile solution of di-cyclo-hexane-18-crown-6 on evaporation. The mol-ecule is arranged around a center of symmetry with half the crown ether mol-ecule and one mol-ecule of aceto-nitrile symmetry independent. All O-C-C-O torsion angles are gauche while all C-O-C-C angles are trans. The sequence of torsion angles is [(tg(+)t)(tg(-)t)]3; the geometry of oxygen atoms is close to pseudo-D 3d with three atoms below and three atoms above the mean plane, with an average deviation of ±0.16 (1) Å from the mean plane. This geometry is identical to that observed in metal ion complexes of di-cyclo-hexane-18-crown-6 but differs significantly from the conformation of a free unsolvated mol-ecule. Each aceto-nitrile mol-ecule connects to a crown ether mol-ecule via two of its methyl group H atoms (C-H⋯O). Weaker inter-actions exist between the third H atom of the aceto-nitrile methyl group and an O atom of a neighbouring crown ether mol-ecule (C-H⋯O); and between the N atom of the aceto-nitrile mol-ecule and a H atom of another neighbouring crown ether mol-ecule. All these inter-molecular inter-actions create a three-dimensional network stabilizing the disolvate.

Bis(isonicotinamide-κ<i>N</i>)silver(I) tri-fluoro-methane-sulfonate aceto-nitrile disolvate.

Project description:The central AgI atom of the title salt, [Ag(INAM)2](CF3SO3)·2CH3CN, where INAM is isonicotinamide (C6H6N2O), is twofold coordinated by the pyridine N atoms of two isonicotinamide ligands creating a slightly distorted linear mol-ecular geometry. The formation of polymeric chains {[Ag(INAM)2]+} n , held together by discrete hydrogen bonds through the amide group of the INAM ligand leaves voids for non-coordinating aceto-nitrile mol-ecules that inter-act the silver metal center via regium bonds.

Crystal structure of bis-[(acetato-κO)(imidazolidine-2-thione-κS)bis-(tri-phenyl-phosphane-κP)silver(I)] di-μ-imidazol-idine-2-thione-κ(4) S:S-bis-[(imidazol-id-ine-2-thione-κS)bis-(tri-phenyl-phosphane-κP)silver(I)] di-acetate aceto-nitrile disolvate tetra-hydrate.

Project description:In the title compound, [Ag2(C3H6N2S)4(C18H15P)2](C2H3O2)2·[Ag(C2H3O2)(C3H6N2S)(C18H15P)2]2·2C2H3N·4H2O, the Ag(I) ion in the mononuclear neutral complex exhibits a distorted tetra-hedral environment with coordination by two P atoms from tri-phenyl-phosphane (PPh3) ligands, one S atom of an imidazolidine-2-thione (etu) ligand and one O atom of an acetate anion. The binuclear cationic complex comprises two inversion-related [Ag(C3H6N2S)2(C18H15P)] units with Ag(I) ions bridged by two S atoms from etu ligands forming a four-membered Ag-S-Ag-S ring. Each Ag(I) ion is coordinated by a P atom of a PPh3 ligand, two S atoms of bridging etu ligands and the terminal S atom of an etu ligand in a distorted tetra-hedral environment. In the crystal, the mononuclear complex is linked to lattice water mol-ecules through O-H⋯O and N-H⋯O hydrogen bonds, forming a chain along [100]. In addition, the binuclear complex mol-ecules are connected to acetate anions and lattice water mol-ecules via O-H⋯O, N-H⋯O and O-H⋯S hydrogen bonds, also along [100].

Tris(aceto-nitrile-?N)dichlorido(tri-phenyl-phosphane-?P)ruthenium(II) aceto-nitrile monosolvate.

Project description:In the title complex, [RuCl2(CH3CN)3(C18H15P)]·CH3CN, the coordination geometry of the Ru(II) atom is distorted octa-hedral, defined by one P atom from a tri-phenyl-phosphane ligand, three N atoms from three aceto-nitrile ligands and two Cl atoms. The three acetronitile ligands linearly bind to the Ru(II) atom, with Ru-N-C angles of 172.6?(2), 179.9?(2) and 171.4?(2)°.

?-Hexa-thio-metadiphosphato-bis-[(1,4,7,10,13,16-hexa-oxa-cyclo-octa-decane-?(6) O)rubidium] aceto-nitrile disolvate.

Project description:The asymmetric unit of the title compound, [Rb2(P2S6)(C12H24O6)2]·2CH3CN, contains one half of an [Rb(18-crown-6)2]2[P2S6] unit and one aceto-nitrile solvent mol-ecule. The [Rb(18-crown-6)]2[P2S6] unit is completed by inversion symmetry. Its Rb(+) ion is situated near the centre of the macrocyclic cavity, but is displaced by 0.8972?(1)?Å from the O atoms of the crown in the direction of the [P2S6](2-) moiety. The overall coordination number of the cation is eight, defined by the six crown ether O atoms and by two terminal S atoms of the [P2S6](2-) anion. The hexa-thio-metadiphosphate anion is built up from two tetra-hedral PS4 units joined together by a common edge. The crystal structure is characterized by alternating layers of [Rb(18-crown-6)]2[P2S6] and aceto-nitrile solvent mol-ecules stacked along [010].

(Meth-oxy-methyl-idene)di-methyl-aza-nium tetra-phenyl-borate aceto-nitrile monosolvate.

Project description:In the cation of the title salt, C4H10NO(+)·C24H20B(-)·C2H3N, the C-N bond lengths are 1.2864 (16), 1.4651 (17) and 1.4686 (16) Å, indicating double- and single-bond character, respectively. The C-O bond length of 1.2978 (15) Å shows double-bond character, pointing towards charge delocalization within the NCO plane of the iminium ion. C-H⋯π inter-actions are present between the methine H atom and two of the phenyl rings of the tetra-phenyl-borate ion. The latter forms an aromatic pocket in which the cation is embedded. The iminium ion is further connected through a C-H⋯N hydrogen bond to the aceto-nitrile mol-ecule. This leads to the formation of a two-dimensional supramolecular pattern along the bc plane.
