N,N,N',N'-Tetra-methyl-guanidinium tetra-phenyl-borate.

ABSTRACT: In the title salt, C5H14N3(+)·C24H20B(-), the C-N bond lengths in the central CN3 unit are 1.3322?(11), 1.3385?(12) and 1.3422?(12)?Å, indicating partial double-bond character. The central C atom is bonded to the three N atoms in a nearly ideal trigonal-planar geometry [N-C-N angles = 119.51?(8), 119.81?(9) and 120.69?(8)°] and the positive charge is delocalized in the CN3 plane. The bond lengths between the N atoms and the terminal methyl groups all have values close to a typical single bond [1.4597?(12)-1.4695?(13)?Å]. The crystal packing is caused by electrostatic inter-actions between cations and anions.

3-Methyl-4,5-di-hydro-oxazolium tetra-phenyl-borate.

Project description:In the cation of the title salt, C4H8NO(+)·C24H20B(-), the C-N bond lengths are 1.272?(2), 1.4557?(19) and 1.4638?(19)?Å, indicating double- and single-bond character, respectively. The C-O bond length of 1.3098?(19)?Å shows that double-bond character and charge delocalization occurs within the NCO plane of the cation. In the crystal, a C-H?? inter-action is present between the methyl-ene H atom of the cation and one phenyl ring of the tetra-phenyl-borate ion. The latter forms an aromatic pocket in which the cation is embedded.

Project description:In the title salt, C15H36N6 (2+)·2C24H20B(-), the three N-C bond lengths in the central C3N unit of the bis-amidinium ion range between 1.388 (3) and 1.506 (3) Å, indicating single- and double-bond character. Furthermore, four C-N bonds have double-bond character. Here, the bond lengths range from 1.319 (3) to 1.333 (3) Å. Delocalization of the positive charges occurs in the N/C/N and C/N/C planes. The dihedral angle between both N/C/N planes is 70.5 (2)°. In the crystal, C-H⋯π inter-actions between H atoms of the cation and the benzene rings of both tetra-phenyl-borate ions are present. The benzene rings form aromatic pockets, in which the bis-amidinium ion is embedded. This leads to the formation of a two-dimensional supra-molecular pattern along the ab plane.

In addition, C-H⋯π inter-actions involving guanidinium H atoms and aromatic rings of the anion are present. The phenyl rings form aromatic pockets, in which the cations are embedded. This leads to the formation of a two-dimensional supramolecular pattern along the ab plane.

The bonds between the N atoms and the terminal C-methyl groups of the guanidinium moiety have values in the range 1.459?(4)-1.478?(4)?Å, close to a typical single bond. In the crystal, there are C-H?? inter-actions between the guanidinium H atoms and the phenyl rings of the tetra-phenyl-borate ion. These inter-actions combine to form a ladder of linked chains of ions which runs parallel to the c axis.

[1,4-Phenyl-enebis(methyl-ene)]bis-(tri-phenyl-phospho-nium) bis-(tetra-fluoro-borate).

Project description:The crystal structure of the title salt, C(44)H(38)P(2) (2+)2BF(4) (-), consists of discrete dications inter-laced with the BF(4) (-) counter-ions. In each cation, both phospho-nium groups lie on the same side of the plane of the central benzene ring. The tetra-fluoro-borate anions are involved in intensive thermal motion, thus some B-F bond lengths [range 1.329?(6) to 1.391?(6)?Å] deviate significantly from their standard values.
