Crystal structure and catalytic activity of tetra-kis-(μ2-ethyl 2,6-di-tert-butyl-4-methyl-phenyl phos-phato-κ2O:O')bis-(ethyl 2,6-di-tert-butyl-4-methyl-phenyl phosphato-κ2O,O')dilutetium n-heptane disolvate.

ABSTRACT: The title complex, [Lu2(C17H28O4P)6]·2C7H16, was formed in the reaction between potassium 2,6-di-tert-butyl-4-methyl-phenyl ethyl phosphate, [K(2,6- t Bu2-4-MeC6H2-O)(EtO)PO2], and LuCl3(H2O)6 in water, followed by vacuum drying and recrystallization from heptane. Its crystal structure has triclinic (P [Formula: see text]) symmetry at 120 K. The lutetium tris-(phosphate) complex has a binuclear [Lu2(μ-OPO)4] core and the organophosphate ligand exhibits κ2O,O' terminal and μ2-κ1O:κ1O' bridging coordination modes with the LuIII ion being sixfold coordinated. The complex is of inter-est as a precatalyst in the acrylo-nitrile polymerization process and displays good catalytic activity under mild conditions.

{2,6-Bis[(di-tert-butyl-phosphino)-methyl]-phenyl}chloridonickel(II).

Project description:In the title compound, [Ni(C(24)H(43)P(2))Cl], the Ni atom adopts a distorted square-planar geometry, with the P atoms of the 2,6-bis-[(di-tert-butyl-phosphino)meth-yl]phenyl ligand trans to one another. The P-Ni-P plane is twisted out of the plane of the aromatic ring by 21.97?(6)°.

2,6-Di-tert-butyl-4-[(N-methyl-anilino)meth-yl]phenol.

Project description:The title compound, C(22)H(31)NO, has been synthesized from 4-bromo-methyl-2,6-di-tert-butyl-phenol and N-methyl-aniline. There are two independent mol-ecules in the asymmetric unit. The aniline ring in each of the independent mol-ecules was found to be disordered, with site occupation factors 0.621?(10)/0.379?(10) and 0.605?(10)/0.395?(10).

3,3'-Di-tert-butyl-1,1'-[1,3-phenyl-enebis(methyl-ene)]diurea.

Project description:The title compound, C(18)H(30)N(4)O(2), contains two tert-butyl urea groups, each connected to a benzene ring though a methyl-ene group. One of the groups occupies a position almost normal to the aromatic plane with a C-N-C-C torsion angle of -94.4?(4)°, while the other is considerably twisted from the ring with a C-N-C-C torsion angle of -136.1?(4)°. In the crystal, pairs of mol-ecules are connected to each other, forming centrosymmetric dimers in which two NH groups of one mol-ecule act as hydrogen-bond donors to one carbonyl O atom of the other mol-ecule. The dimers are linked into sheets parallel to (100) by N-H?O hydrogen bonds involving the remaining N-H and C=O groups.

2,4-Di-tert-butyl-6-[1-(3,5-di-tert-butyl-2-hydroxy-phen-yl)eth-yl]phenyl 4-methyl-benzene-sulfonate.

Project description:The title compound, C(37)H(52)O(4)S, was obtained by the reaction of 6,6'-(ethane-1,1-di-yl)bis-(2,4-di-tert-butyl-phenol) and 4-methyl-benzene-1-sulfonyl chloride. The mol-ecular conformation is stabilized by an intra-molecular O-H?O hydrogen bond. Two of the tert-butyl groups are disordered over two sets of sites with occupancies 0.530?(15)/0.470?(15) and 0.615?(11)/0.385?(11).

6,6'-Di-tert-butyl-2,2'-[1,2-phenyl-ene-bis(nitrilo-methyl-idyne)]diphenol.

Project description:The mol-ecule of the title Schiff base compound, C(28)H(32)N(2)O(2), has a twisted geometry, the dihedral angles between the central benzene ring and the other two benzene rings being 29.12?(14) and 26.01?(14)°. Four intra-molecular C-H?O hydrogen bonds and two intra-molecular O-H?N hydrogen bonds stabilize the mol-ecular structure. In the crystal packing, mol-ecules are stacked along the a axis and stabilized by ?-? inter-actions [centroid-centroid distance = 3.6724?(17)?Å]. The crystal studied was found to be a non-merohedral twin, the refined ratio of twin components being 0.374?(5):0.626?(5).

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.
