Crystal structure of bis-(aceto-nitrile-?N)(4,4'-di-tert-butyl-2,2'-bi-pyridine-?2N,N')platinum(II) bis-(tetra-fluorido-borate) packing as head-to-head dimers.

ABSTRACT: The crystal structure of a platinum(II) supra-molecular building block, [Pt(dbbpy)(NCCH3)2](BF4)2 (dbbpy = 4,4'-di-tert-butyl-2,2'-bi-pyridine, C18H24N2) is an example of a rare head-to-head dimer, even with the bulky tert-butyl groups of the bi-pyridine. This packing motif still enables significant ?-? inter-actions between two pyridyl groups, and may result from the close proximity of the tetra-fluorido-borate ions to the platinum(II) complexes, resulting in intra-molecular H?F distances between 2.156 and 2.573?Å.

Hexakis(acetonitrile-κN)ruthenium(II) bis-(hexa-bromo-carbadodeca-borate) aceto-nitrile solvate.

Project description:The title compound, [Ru(NCCH(3))(6)](CH(6)B(11)Br(6))(2)·CH(3)CN, consists of the 'naked' ruthenium(II) cation surrounded by six acetonitrile mol-ecules, each coordinated via the nitro-gen atoms in a linear or nearly-linear fashion in a typical octa-hedral over-all arrangement. The cation is balanced by the two hexa-bromo-carborane cage anionic fragments [CB(11)H(6)Br(6)]. Weak C-H⋯Br and B-H⋯Br inter-actions link neighboring anions.

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-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)°].

Crystal structure of catena-poly[[[di-aqua-cobalt(II)]-bis-(μ-hex-3-enedi-nitrile-κ(2) N:N')] bis-(tetra-fluorido-borate)].

Project description:In the structure of the title salt, [Co(C6H6N2)2(H2O)2](BF4)2, the Co(II) atom is located on an inversion centre. The transition metal is in a slightly distorted octa-hedral coordination environment, defined by the cyano N atoms of four hex-3-enedi-nitrile ligands in equatorial positions and the O atoms of two water mol-ecules in axial positions. The bridging mode of the hex-3-enedi-nitrile ligands leads to the formation of cationic chains extending parallel to [1-10]. The BF4 (-) counter-anion is disordered over two sets of sites [occupancy ratio = 0.512 (19):0.489 (19)]. It is located in the voids between the cationic chains and is connected to the aqua ligands of the latter through O-H⋯F hydrogen bonds. One methyl-ene H atom of the hex-3-enedi-nitrile ligand forms another and weak C-H⋯O hydrogen bond with a water O atom of a neighbouring chain, thus consolidating the three-dimensional network structure.

1-(2-Methyl-phen-yl)-4,4'-bipyridin-1-ium tetra-fluorido-borate.

Project description:Crystals of the title compound, C17H15N2 +·BF4 -, were unexpectedly grown from crystallization attempts of [Pt(4,4'-bpy)4](BF4)2 [Smith et al. (2019 ▸). Comments Inorg. Chem. 39, 188-215] using toluene and aceto-nitrile. The tetra-fluoro-borate anion and the central pyridinium ring of the cation are disordered, with atomic site occupancies close to ½. The tolyl group of the cation has a 75.31 (11)° twist relative to the unsubstituted pyridyl group. This rotation allows for a centrosymmetric dimer of cations with weak hydrogen bonding between the pyridyl nitro-gen atom and a methyl H atom on the neighbouring cation.

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.

(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.
