Molecular and electronic structure of penta- and hexacoordinate silicon compounds

Bromination of silatranyl‐, germatranyl‐, silyl‐, and germyl‐phenylacetylenes

“…Investigation of metallatranes by using different spectroscopic and other physical methods permits to form a general idea about their electronic nature and bonding [1]. It should be noted that the observed changes in physical properties and reactivity successfully correlate with those in the transannular M ← N bond length [2,6]. The latter and a number of other reasons cause metallatranes to make a significant contribution to the theoretic organometallic chemistry.…”

“…Among them metallatranes of the group 14 elements have been investigated rather in detail by the present time [1][2][3][4][5].…”

“…(1) (2) The triple bond of (trialkylsilyl)alkynes R 3 SiC CH (R = Me, Et) vigorously adds Br 2 without solvent, one molecule of bromine adding at 20-50…”

Novel hexacoordinate organosilicon(IV) complexes of diethylenetriamine Schiff base with SiO2N3 skeleton

“…The chemistry of complexes with hypercoordinate silicon atoms is interesting from many points of view such as reactivity, biological activity and structural features as reported in several reviews [3][4][5] . Wagler and co-workers [6][7][8][9][10] synthesized a large number of hypercoordinated complexes of silicon by using different salen and salphen type ligands and studied their reactivity.…”

Synthesis, Characterization and Antifungal Studies of Organosilicon (IV) Complexes Derived From Mixed Azines

“…The chemistry of complexes with hyper-coordinate silicon atoms is interesting from many points of view such as reactivity, biological activity and structural features as reported in several reviews [6][7][8] . A survey of literature reveals that the present stage of knowledge about the organosilicon complexes of mixed azines containing N, O donor system is rather scanty.…”
