Bis(1,2,2,6,6-penta-methyl-piperidin-4-yl) 2-butyl-2-(3,5-di-tert-butyl-4-hydroxy-benz-yl)malonate (Tinuvin 144).

ABSTRACT: The title compound, C(42)H(72)N(2)O(5), a hindered amine light stabiliser (HALS) with the trade name Tinuvin 144 was prepared from bis-(1,2,2,6,6-penta-methyl-piperidin-4-yl) 2-butyl-malonate and 2,6-di-tert-butyl-4-[(dimethyl-amino)meth-yl]phenol using lithium amide as a catalyst. In the mol-ecule, both piperidine rings adopt chair conformations. In the crystal, inversion dimers linked by pairs of O-H?O hydrogen bonds occur.

Diethyl 2,2-bis-(3,5-di-tert-butyl-4-hy-droxy-benz-yl)malonate.

Project description:The title mol-ecule, C(37)H(56)O(6), possesses twofold symmetry, with the twofold axis passing through the quaternary C atom. In the crystal, neighbouring mol-ecules are linked via O-H?O hydrogen bonds involving the phenol OH group and the carbonyl O atom, forming chains propagating in [101]. Within these chains, rings are formed with an R(2) (2)(20) motif. There are also C-H?O inter-actions present within the rings.

catena-Poly[[triphenyl-tin(IV)]-?-2-[(3,5-di-tert-butyl-4-hydroxy-benz-yl)sulfan-yl]acetato-?O:O'].

Project description:The title compound, [Sn(C(6)H(5))(3)(C(17)H(25)O(3)S)](n), comprises two symmetry-independent five-coordinated triphenyl-tin mol-ecules which are linked by carboxyl-ate bridges into a polymeric chain. The Sn(IV) atom is in a distorted trans-C(3)SnO(2) trigonal-bipyramidal geometry. The presence of two bulky tert-butyl groups on the benzene ring prevents any hydrogen-bonding inter-actions involving the hydroxyl substituents.

Project description:The title compound, (C(21)H(33)N(2)O)(2)[SmCl(5)(C(4)H(8)O)]·C(7)H(8)·C(4)H(8)O, has a layered structure in which each distorted octa-hedral [SmCl(5)(THF)](2-) unit (THF is tetra-hydro-furan) is capped by two cations. The central metal Sm(III) atom of the [SmCl(5)(THF)](2-) anionic unit is coordinated by five Cl atoms and one THF O atom, forming a distorted octa-hedral geometry. The crystal structure displays C-H?Cl and O-H?Cl hydrogen bonding. The structure exhibits disorder of the solvent.

Project description:The title compound, C(20)H(32)N(2)O(2)S, the condensation product of a thio-acetohydrazine and acetone, has a two-coordinate S atom and the angle at this atom is 100.7?(1)°. The (CH(3))C=N-NH-C(O)- substituent engages in N-H?O hydrogen-bonding inter-actions with the substituent of an adjacent mol-ecule across a center of inversion, generating a dimeric structure.

Di-n-butyl-ammonium 2-[(3,5-di-tert-butyl-4-hy-droxy-benz-yl)sulfan-yl]benzoate.

Project description:The title salt, C(8)H(20)N(+)·C(22)H(27)O(3)S(-), is a proton-transfer compound derived from the recently reported parent carb-oxy-lic acid [Alhadi et al. (2010). Acta Cryst. E66, o1787] by the addition of a second equivalent of di-n-butyl-amine, yielding the di-n-butyl-ammonium carboxyl-ate salt. The structure of the carboxyl-ate anion resembles that of the parent carb-oxy-lic acid. The main difference lies in the position of the H atom in the 4-hy-droxy group. In the anion the O-H bond is perpendicular, rather than parallel, to the benzyl ring. This position appears to facilitate hydrogen bonding to an O atom of the carboxyl-ate group of a symmetry-related anion. In addition, there are three N-H⋯O hydrogen bonds. In contrast, the neutral species hydrogen bonds via a carboxylic acid dimer. The dihedral angle between the benzene rings in the anion is 79.19 (7)°.

Ethyl 4-[(3,5-di-tert-butyl-2-hy-droxy-benz-yl)amino]-benzoate.

Project description:The title amine, C(24)H(33)NO(3), has two substituted aromatic rings at either end of the -CH(2)NH- linkage [C(ar-yl)-CH(2)-NH-C(ar-yl) torsion angle = 77.4 (3)°]. The amino and hy-droxy groups are hydrogen-bond donors to the carbonyl O atom of an adjacent mol-ecule. These hydrogen bonds give rise to a chain that runs along the b axis. One of the tert-butyl groups is disordered over two positions with a site-occupation factor of 0.834 (6) for the major occupied site.
