Crystal structure of tris-(?-bis-{4-[(pyridin-2-yl-methyl-idene)amino]-phen-yl}methane-?(4) N,N':N'',N''')dizinc tetra-kis-(tetra-fluorido-borate) aceto-nitrile tris-olvate.

ABSTRACT: The asymmetric unit of the title compound, [Zn2(C25H20N4)3](BF4)4·3CH3CN, consists of one dinuclear Zn(II) complex cation with a triple-helical [Zn2 L 3](4+) motif (L is bis-{4-[(pyridin-2-yl-methyl-idene)amino]-phen-yl}methane), four BF4 (-) anions and three CH3CN solvent mol-ecules. The Zn?Zn separation is 11.3893?(14)?Å and the ligands wrap around the two Zn(II) atoms, forming a triple helix as defined by the Zn-N-N-Zn torsion angles of 104.05?(18), 99.06?(19) and 101.40?(19)°. The Zn-N(pyrid-yl) distances in the octahedral ZnN6 coordination sphere are in the range 2.128?(5)-2.190?(5)?Å and the Zn-N(imine) distances are in the range 2.157?(5)-2.277?(5)?Å.

Project description:In the title compound, rac-[Ru(C14H16N2)2(C16H8N4)](PF6)2·3C2H3N, discrete dimers of complex cations, [Ru(tmbpy)2-tape](2+), of opposite chirality are formed (tmbpy = tetra-methyl-bipyridine; tape = tetraazaperylene), held together by ?-? stacking inter-actions between the tetra-aza-perylene moieties with centroid-centroid distances in the range 3.563?(3)-3.837?(3)?Å. These inter-actions exhibit a parallel displaced ?-? stacking mode. Additional weak C-H??-ring and C-H?N and C-H?F inter-actions are found, leading to a three-dimensional architecture. The Ru(II) atom is coordinated in a distorted octa-hedral geometry. The counter-charge is provided by two hexa-fluorido-phosphate anions and the asymmetric unit is completed by three aceto-nitrile solvent mol-ecules of crystallization. Four F atoms of one PF6 (-) anion are disordered over three sets of sites with occupancies of 0.517?(3):0.244?(3):0.239?(3). Two aceto-nitrile solvent mol-ecules are highly disordered and their estimated scattering contribution was subtracted from the observed diffraction data using the SQUEEZE option in PLATON [Spek (2009 ?).

Tetra-kis(triphenyl-phosphane-?P)silver(I) tetra-fluorido-borate.

Project description:The title complex, [Ag(C(18)H(15)P)(4)]BF(4), was prepared by the reaction of silver(I) tetra-fluorido-borate and triphenyl-phosphane in the presence of 1,2-bis-(pyridin-2-yl)ethyl-ene. The Ag(I) atom is tetra-hedrally coordinated by four P atoms from triphenyl-phosphane (PPh(3)) ligands. Due to symmetry, the tetra-fluorido-borate anion is disordered over three positions (each with one third occupancy). The tetra-fluorido-borate anion does not coordinate to the Ag(I) atom.

Tetra-kis(aceto-nitrile)copper(I) hydrogen oxalate-oxalic acid-aceto-nitrile (1/0.5/0.5).

Project description:In the title compound, [Cu(CH3CN)4](C2HO4)·0.5C2H2O4·0.5CH3CN, the Cu(I) ion is coordinated by the N atoms of four aceto-nitrile ligands in a slightly distorted tetra-hedral environment. The oxalic acid mol-ecule lies across an inversion center. The aceto-nitrile solvent mol-ecule is disordered across an inversion center and was refined with half occupancy. In the crystal, the hydrogen oxalate anions and oxalic acid mol-ecules are linked via O-H?O hydrogen bonds, forming chains along [010].

Tetra-aceto-nitrile-lithium tetra-iso-thio-cyanato-borate.

Project description:The crystal structure of the title salt, [Li(CH3CN)4][B(NCS)4], is composed of discrete cations and anions. Both the Li and B atoms show a tetra-hedral coordination by four equal ligands. The aceto-nitrile and iso-thio-cyanate ligands are linear. The bond angles at the B atom are close to the ideal tetra-hedral value [108.92?(18)-109.94?(16)°], but the bond angles at the Li atom show larger deviations [106.15?(17)-113.70?(17)°].

Project description:In the title compound, Na(+)·4C(7)H(5)N(6) (+)·5BF(4) (-), the Na(+) ion lies on a fourfold rotation axis and one of the tetra-fluoridoborate ions lies on a site of symmetry . Each Na(+) ion is surrounded by four symmetry-related tetra-fluoridoborate ions, and is eight-coordinated by F atoms, the Na?F separation being 2.3956?(15) or 2.4347?(17)?Å. The hexa-azaphenalenium ring system is essentially planar. In the crystal structure, the cations and anions are linked into a three-dimensional network by N-H?N and C-H?F hydrogen bonds.

(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.

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

Project description:In the title solvated salt, C7H16NO(+)·C24H20B(-)·C2H3N, the C-N bond lengths in the cation are 1.2831 (19), 1.467 (2) and 1.465 (2) Å, indicating double- and single-bond character, respectively. The C-O bond length of 1.2950 (18) Å shows a double-bond character, pointing towards charge delocalization within the NCO plane of the iminium ion. The two C atoms of the n-butyl group are disordered over the two sites, with refined occupancy ratios of 0.890 (5):0.110 (5) and 0.888 (4):0.112 (4). In the crystal, C-H⋯π inter-actions occur between the methine H atom, H atoms of the -N(CH3)2 and -CH2 groups of the cation, and two of the phenyl rings of the tetra-phenyl-borate anion. The latter inter-action forms an aromatic pocket in which the cation is embedded. Thus, a two-dimensional pattern is created in the ac plane.

Project description:In the title compound, [Ir(C11H8N)2(C28H20N8)](PF6)3·3CH3CN or [Ir(III)(ppy)2{(2-pym)2qpy(2+)}](PF6)3·3CH3CN (ppy = deprotonated 2-phenyl-pyridine, pym = pyrimidyl and qpy = 4,4':2',2'':4'',4'''-quaterpyrid-yl), the Ir(3+) cation is coordinated by two C atoms and four N atoms in a slightly distorted octa-hedral geometry. The asymmetric unit consists of one complex trication, three hexa-fluorido-phosphate anions and three aceto-nitrile solvent mol-ecules. The average Ir-C distance is 2.011 (14) Å, the average Ir-N(ppy) distance is 2.05 (6) Å and the average Ir-N(qpy) distance is longer at 2.132 (10) Å. The dihedral angles within the 4,4'-bipyridyl units are 31.5 (6) and 23.8 (7)°, while those between the 2-pym and attached pyridyl rings are rather smaller, at 11.7 (9) and 7.1 (9)°. The title compound was refined as a two-component inversion twin.

Crystal structure of bis-(2,2'-bi-pyridine)[N'-(quino-lin-2-ylmethylidene)pyridine-2-carbohydrazide]ruthenium(II) bis(tetra-fluorido-borate) di-chloro-methane tris-olvate.

Project description:The title compound, [Ru(C10H8N2)2(C16H12N4O)](BF4)2·3CH2Cl2, crystallizes with one complex dication, two BF4 (-) counter-anions and three di-chloro-methane solvent mol-ecules in the asymmetric unit. The central Ru(II) atom adopts a distorted octa-hedral coordination sphere with two 2,2'-bi-pyridine (bpy) and one quinoline-2-carbaldehyde (pyridine-2-carbon-yl)hydrazone (HL) ligand. The hydrazone ligand has a Z form and coordinates to the Ru(II) atom via the amide-O and imine-N atoms, affording a planar five-membered chelate ring, while its pyridine-N and quinoline-N donor atoms in the substituents are non-coordinating. The hydrazone N-H group forms an intra-molecular hydrogen bond with the quinoline-N atom. In the crystal, the quinoline moiety of HL shows the shortest ?-? stacking inter-action with the pyridine substituent of HL in a neighbouring complex, the centroid-to-centroid distance being 3.793?(3)?Å.
