ABSTRACT: 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. The inter-planar angles between pairs of the three benzene rings of the 4-methyl-phenyl-sulfonyl units are 41.15?(10), 18.11?(10) and 44.09?(10)°. 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.

Bis[?-N-(tert-butyl-dimethyl-silyl)-N-(pyridin-2-ylmeth-yl)amido]-bis-[methyl-cobalt(II)].

Project description:The green title complex, [Co(2)(CH(3))(2)(C(12)H(21)N(2)Si)(2)], was obtained from bis-{[?-N-tert-butyl-dimethyl-silyl-N-(pyridin-2-ylmeth-yl)amido]-chloridocobalt(II)} and methyl-lithium in diethyl ether at 195?K via a metathesis reaction. The dimeric cobalt(II) complex exhibits a crystallographic center of inversion in the middle of the Co(2)N(2) ring (average Co-N = 2.050?Å). The Co(II) atom shows a distorted tetra-hedral coordination sphere. The exocyclic Co-N bond length to the pyridyl group shows a similar value of 2.045?(4)?Å. The exocyclic methyl group has a rather long Co-C bond length of 2.019?(5)?Å.

[1-Dimethyl-silyl-2-phenyl-3-(?-tetra-methyl-cyclo-penta-dien-yl)-prop-1-en-1-yl-?C](?-penta-methyl-cyclo-penta-dien-yl)titanium(III).

Project description:The title compound, [Ti(C(10)H(15))(C(20)H(26)Si)], was obtained from the reaction of [Ti{?(5):?(1)-C(5)Me(4)(CH(2))}(?(5)-C(5)Me(5))] with the alkynylsilane PhC(2)SiMe(2)H. The complex crystallizes with two independent mol-ecules in the asymmetric unit, which differ in the conformation of the propenyl unit, resulting in their having opposite helicity. No inter-molecular inter-actions or inter-actions involving the Si-H bond are present. The observed geometrical parameters are unexceptional compared to known structures of the same type.

In the crystal, pairs of inter-molecular C-H⋯π inter-actions form centrosymmetrical dimers, which are linked by weak inter-molecular C-H⋯O hydrogen bonds.
