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 oc...

The title compound, C(14)H(19)N(2) (+)·BF(4) (-), was obtained by reaction of 1-ethyl-3-(2,4,6-trimethyl-phen-yl)imidazolium tetra-fluoro-borate with sodium tetra-fluoro-borate. The imidazole ring makes a dihedral angle of 78.92 (13)° with the benzene ring.

The title compound, [Na(C(16)H(36)BO(4))](n), has a fourfold axis passing through the Na and B atoms which both are bound by four O atoms. The tetra-butoxy-borate anion provides the bridging to form one-dimensional polymers running along [001], just like those found for the tetra-ethoxy-borate structure. The two but-oxy 'tail' atoms are disordered over two conformations in a 0.887 (9):0.113 (9)...

In this article,the dissolution of Boric acid in different temperature conditions, with density functional theory (DFT) is studied.  the Boric acid with chemical formula H3BO3 (sometimes written B(OH)3), and exists in the form of colorless crystals or a white powder that dis...

In the title salt, C(19)H(15)N(4) (+)·C(24)H(20)B(-), the tetra-phenyl-borate anion is in a tetra-hedral geometry around the B atom [C-B-C angles of 107.10 (9)-111.79 (9)°]. In the cation, the tetra-zole ring makes dihedral angles of 3.04 (7), 51.75 (7) and 51.13 (7)° with the attached phenyl rings. In the crystal, C-H⋯π inter-actions link the cations and anions into ion pairs.

The title ionic salt, C21H20P(+)·C24H20B(-), crystallized with two independent vinyl-tri-phenyl-phospho-nium cations and two independent tetra-phenyl-borate anions per asymmetric unit. These four independent moieties contain nearly perfect tetra-hedral symmetry about their respective central C atoms. In the crystal, there are no π-stacking or other inter-molecular inter-actions present.

The improved synthesis and characterization of tetra-pyrazine-platinum(II) bis-(tetra-fluoro-borate) acetonitrile hemisolvate, [Pt(C(4)H(4)N(2))(4)](BF(4))(2)·0.5CH(3)CN, is reported. The unit cell contains a half equivalent of an acetonitrile solvent mol-ecule per tetra-pyrazine-platinum(II) ion. The coordination geometry of the Pt(II) ion is almost square-planar, with the Pt atom residing on ...

The title ionic compound, C16H36N(+)·C10H20B10N3O3(-), consists of a tetra-butyl-ammonium cation and a closo-deca-borate cluster anion, which is bound to the substituted 2,3-dihydro-1,2,4-oxadiazole ring through a B-N bond [1.540 (2) Å]. The distances between connected B atoms in the deca-borate cluster range from 1.689 (2) to 1.844 (2) Å. The 2,3-dihydro-1,2,4-oxadiazole ring adopts an envelop...

The centrosymmetric title compound, [Cu(2)(C(10)H(8)N(2))(2)(C(25)H(22)P(2))(2)](BF(4))(2), consists of discrete dinuclear cations and tetra-fluoro-borate anions. The two Cu(I) centers are bridged by the phosphine ligands to form an eight-membered ring. The Cu(I) center exhibits a tetra-hedral coordination as it is chelated by the N-heterocycle.

The title compound, KZnB(3)O(6) contains a remarkable [B(6)O(12)](6-) group ( symmetry) formed by two rings linked by edge-sharing BO(4) tetra-hedra, a feature that has only been observed previously under high pressure conditions. These borate groups are connected through distorted ZnO(4) tetra-hedra in edge-shared pairs ( symmetry), forming a three-dimensional network whose cavities are filled...
