evidence54 indicate that the bonding is better described as a single dative bond
with anionic lO — character. The usual hyperconjugative interactions (Section 3.4
.2) between oxygen lone pairs and vicinal hydride antibonds are expected to ...

Group 13 Chemistry III: Industrial Applications
The steric bulk of the f-Bu group blocks the nitrogen from forming a dative bond.
For the other compounds, it was clear which 0 was covalently bound and which
was bridging simply by comparing bond lengths; the covalent bonds were ...

Chemical Bonding at Surfaces and Interfaces
Pyridine, a six-membered cyclic aromatic amine, has also been studied on Ge(
100)–2×1 both theoretically [315,316] and experimentally by STM [314]. It
adsorbs selectively through a Ge−N dative bond on the surface. Theoretical
calculations ...

intermolecular interactions significantly depends on the reverse dative bond
existing in the molecules of the alkyl compounds (Fig. 1.3). The divergence of the
regular ...

Functionalization of Semiconductor Surfaces
Because the down atom is electron deficient, it can react with a Lewis base to
form a dative bond (see Fig. 8.2a) [3]. In contrast, the electron-rich up atom can
donate its electron density to a Lewis acid to form a dative bond (see Fig. 8.2b).

3.5 DATIVE BOND (Co-ordinate-covalent bond) A dative bond is basically a
covalent bond with more pronounced ionic character. A | dative bond is formed
between an acceptor and a donar atom. The number of dative bonds, an
acceptor is ...
