p-tert-Butylthiacalix[4]arene-supported high-nuclearity {Co24M8} (M=Mo or W) nanospheres and the hybrids with Keggin polyoxometalates.
Two hybrid assemblies (3 and 4) with two kind of nanoscaled cluster units, the spherical [Co(24)(TC4A)(6)(MO(4))(8)Cl(6)](2+) cation (1 and 2) and Keggin-type [PM(12)O(40)](3-) anion (M = Mo (1/3), W (2/4)), were solvothermally prepared and characterized, in which the spherical units are constructed by six Co(4)-p-tert-butylthiacalix[4]arene (Co(4)-TC4A) SBUs linked by eight MO(4) tetrahedrons ...
متن کاملtert-Butoxytriphenylsilane
The title compound, C(22)H(24)OSi or Ph(3)SiO(t)Bu, shows a distorted tetra-hedral coordination sphere around the Si atom. The C-O-Si angle is 135.97 (12)° and the O-Si distance is 1.6244 (13) Å. The mol-ecules are held together by weak inter-actions only. An H⋯H distance of 2.2924 (7) Å is found between aryl H atoms and is the shortest inter-molecular distance in the structure. With regard to ...
متن کامل(R)-N-{2-tert-Butyl-2-[(R)-tert-butylsulfonamido]ethylidene}-tert-butanesulfonamide
The title compound, C(14)H(30)N(2)O(2)S(2), is the product of the monoaddition reaction of tert-butyl magnesium chloride with bis-[(R)-N-tert-butanesulfinyl]ethanediimine. There are two almost identical mol-ecules in the asymmetric unit, the mol-ecular conformation of which is stabilized by an intra-molecular N-H⋯N hydrogen bond.

In the title compound, C(18)H(40)N(2)O(2)S(2), a vicinal diamine derivative, the crystal structure is stabilized by two intra-molecular N-H⋯O hydrogen bonds. The distance between the two kernel chiral C atoms is 1.580 (2) Å.
متن کامل4-tert-Butylpyridinium triiodide–4-tert-butylpyridine (1/1)
The title compound, C(9)H(14)N(+)·I(3) (-)·C(9)H(13)N, consists of monoprotonated 4-tert-butyl-pyridinium cations and triiodide anions. The triiodide ion has near-symmetric linear geometry, with bond lengths of 2.9105 (4) Å (I-I) and a bond angle of 177.55 (3)° (I-I-I). For this room-temperature structure, the butyl group on the pyridine ring is disordered and has been treated as a rigid rotato...
