چکیده مقاله:

Synthesis and cation selectivity of 25, 27, dipropoxy-26, 28, Di-propoxy 5, 11, 17, 23, ptert-butyl Calix[4]arene are studied in acetonitrile solution. The stability constants of differentcomplexes of Calixarene (as a ligand) with alkali metal cations are determined at 25 °C by usingspectrophotometric technique.On the basis of calculations, complexation of Calixarene with Cs+and Li+ are more favored than others. In all cases, it has been shown to form exclusively 1:1(metal ion to ligand) complex with alkali cations in experimental condition.

2,4-Di-tert-butyl-6-[1-(3,5-di-tert-butyl-2-hydroxy­phen­yl)eth­yl]phenyl 4-methyl­benzene­sulfonate

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).

Dichlorido(4,4′-di-tert-butyl-2,2′-bi­pyridine-κ2 N,N′)gold(III) tetrachlorido­aurate(III) acetonitrile solvate

In the title compound, [AuCl(2)(C(9)H(12)N)(2)][AuCl(4)]·C(2)H(3)N, there is a mirror plane passing through Au and the central C-C bond of the bipyridyl ligand in the cation, and through Au and two Cl atoms of the anion. A cis-AuCl(2)N(2) square-planar geometry for the cation and a square-planar AuCl(4) geometry for the anion result. The two C atoms and the N atom of the acetonitrile mol-ecule ...

2,6-Di-tert-butyl-4-(methoxy­meth­yl)phenol

The title compound, C(16)H(26)O(2), was easily obtained in high yield when 4-bromo-methyl-2,6-di-tert-butyl-phenol was reacted with methanol. There are two independent mol-ecules in the asymmetric unit. The meth-oxy group in each of the independent mol-ecules was found to be disordered, with site-occupation factors of 0.8728 (18)/0.1272 (18) and 0.8781 (17)/0.1219 (17).

The title compound, C15H22O3, crystallizes with two independent mol-ecules in the asymmetric unit. In each mol-ecule, one hy-droxy group (at position 2) is involved in an intra-molecular O-H⋯O hydrogen bond, and another one (at position 3) exhibits bifurcated hydrogen-bonding being involved in intra- and inter-molecular O-H⋯O inter-actions. In the crystal, O-H⋯O hydrogen bonds link alternating ...

4,4′-Di-tert-butyl-2,2′-bipyridine

In the title compound, C(18)H(24)N(2), the mol-ecular unit adopts a trans conformation around the central C-C bond [N-C-C-N torsion angle of 179.2 (3)°], with the two aromatic rings almost coplanar [dihedral angle of only 0.70 (4)°]. The crystal packing is driven by co-operative contacts involving weak C-H⋯N and C-H⋯π inter-actions, and also the need to fill effectively the available space.
