Bis[tris(3-tert-butyl-5-methyl-pyrazol-1-yl)hydridoborato]ytterbium(II) toluene solvate.

ABSTRACT: In the title compound, [Yb(C(24)H(40)BN(6))(2)]·C(7)H(8), the Yb atom is coordinated by two tris(3-tert-butyl-5-methyl-pyrazol-1-yl)hydridoborate [Tp(tBu,Me)] ligands. One ligand binds in the ?(3) mode, throuh three N atoms of the pyrazolyl rings, the other ligand coordinates through two N atoms of the pyrazolyl rings and the H atom attached to the central B via an agostic-type inter-action through the B-H group of the second Tp(tBu,Me) ligand, giving an overall distorted octa-hedral geometry. One of the tert-butyl groups is disordered over two sites, with occupancies of 0.65 and 0.35.

In the title compound, [Yb(C(24)H(40)BN(6))(2)]·C(7)H(8), the Yb atom is coordinated by two tris(3-tert-butyl-5-methyl-pyrazol-1-yl)hydridoborate [Tp(tBu,Me)] ligands. One ligand binds in the κ(3) mode, throuh three N atoms of the pyrazolyl rings, the other ligand coordinates through two N atoms of the pyrazolyl rings and the H atom attached to the central B via an agostic-type inter-action through the B-H group of the second Tp(tBu,Me) ligand, giving an overall distorted octa-hedral geometry.

4-tert-Butyl-pyridinium chloride-4,4'-(propane-2,2-di-yl)bis-(2,6-di-methyl-phenol)-toluene (2/2/1).

Project description:In the title solvated salt, C9H14N(+)·Cl(-)·C19H24O2·0.5C7H7, two mol-ecules of 4,4'-(propane-2,2-di-yl)bis-(2,6-di-methyl-phenol) are linked via O-H⋯Cl hydrogen bonds to two chloride ions, each of which is also engaged in N-H⋯Cl hydrogen bonding to a 4-tert-butyl-pyridinium cation, giving a cyclic hydrogen-bonded entity centred at 1/2, 1/2, 1/2. The toluene solvent mol-ecule resides in the lattice and resides on an inversion centre; the disorder of the methyl group requires it to have a site-occupancy factor of 0.5. No crystal packing channels are observed.

Project description:The reaction of (E)-tert-butyl 4-[3-(dimethyl-amino)acrylo-yl]piperidine-1-carboxyl-ate with methyl-hydrazine leads to the formation of the title compound, C(14)H(23)N(3)O(2), with a 1-methyl-1H-pyrazol-5-yl substituent. The plane of the pyrazole ring forms a dihedral angle of 33.4 (1)° with the approximate mirror plane of the piperidine ring.

Inter-molecular C-H⋯π inter-actions between the pyrazole ring H atom and the toluene ring stabilize the crystal structure.

Project description:IN THE TITLE COMPOUND [SYSTEMATIC NAME: (tert-butyl-dimethyl-silyl)methane-triyl tris-(4-methyl-benzene-sulfonate)], C(32)H(44)O(10)S(3)Si, the central C atom and the Si(IV) center are in a tetra-hedral configuration.

C-H?? inter-actions are observed in the crystal structure. Mol-ecules are linked into screw chains along the b axis by weak C-H?O inter-actions. Weak intramolecular C-H?O hydrogen bonds are also present.

(2,6-Bis{5-amino-3-tert-butyl-4-[(3-methyl-1,2,4-thia-diazol-5-yl)diazen-yl]-1H-pyrazol-1-yl}-4-oxo-1,4-dihydro-1,3,5-triazin-1-ido)methanol(phenol)sodium phenol tetra-solvate.

Project description:The title compound, [Na(C(23)H(28)N(17)OS(2))(CH(3)OH)(C(6)H(5)OH)]·4C(6)H(5)OH, is a five-coordinate Na(I) complex. The Na(+) cation is bound to three N atoms of the triazinide ligand, two from each pyrazole ring and one from the central deprotonated triazine ring system. O atoms from a methanol and a phenol mol-ecule complete the five-coordinate NaN(3)O(2) coordination environment. The asymmetric unit also includes three complete and two half phenol mol-ecules, four of which are hydrogen bonded to the N atoms of the thia-diazole ring. Two of the phenol solvent mol-ecules are disordered over two discrete inversion centres. The triazinide ligand is essentially planar (mean deviation from the least-squares plane = 0.0524 Å), with the methyl groups of the tert-butyl substituents on the pyrazole rings located above and below the plane. The planarity of this system is further assisted by the formation of four intra-molecular N-H⋯N hydrogen bonds between the N-H bonds of both amino groups on the pyrazole rings and the N atoms of the triazine ring and also from each of the adjacent diazene (-N=N-) bonds. The highly polar mol-ecules are stacked along the a axis through the central Na atom sandwiched by two kinds of alternating inter-molecular hydrogen bonds: O(carbon-yl)⋯H-O(methanol)/Na/O-H(phenol)⋯O(carbon-yl). These inter-actions form two polymer chains per mol-ecule.
