“…DFT calculations have explored the Lewis acid-Lewis base bonding in Group 14 elements, with the emphasis on silicon complexes with nitrogen donors, and comparisons with germanium analogues [253][254][255][256]. More recently N-heterocyclic carbene adducts have been similarly modelled [257,258].…”

“…The 1,10-phenanthroline adduct of Lewis-acidic stannic chloride was synthesized many years ago (Beattie et al, 1963;Clark et al, 1968;Ohkaku & Nakamoto, 1973;Smith & Wassef, 1975); the adduct has recently been studied theoretically (Davydova et al, 2006). It has been characterized by X-ray crystallography as a 1/4 benzene solvate (Hall & Tiekink, 1996) in which the chelated Sn atom is in an octahedral environment.…”

“…At this point, we turn our attention to the nitrile complexes of GeF 4 . Previous work on the 1:1, Ndonor -GeF 4 complexes includes both experimental [22] and theoretical [23][24][25] studies on the amine-containing systems as well as matrix-isolation-IR studies of the pyridine [26] and nitrile (HCN and CH 3 CN) complexes [27]. Matrix-IR spectra of H 3 N-GeF 4 are consistent with a trigonalbipyramidal geometry about the Ge atom, with the NH 3 subunit bonded in an axial coordination site [22].…”

The 1:1 and 2:1 complexes of FCH 2 CN and ClCH 2 CN with GeF 4 have been investigated by M06/aug-cc-pVTZ calculations, low-temperature, thin-film IR spectroscopy, and an x-ray structure has been obtained for (FCH 2 CN) 2-GeF 4. Theoretical structures and binding energies for FCH 2 CN-GeF 4 and ClCH 2 CN-GeF 4 demonstrate that halogen substitution significantly weakens the Ge-N dative bonds. The Ge-N distances for the F-and Cl-complexes (2.447 and 2.407 Å, respectively) are about 0.2 Å longer than in CH 3 CN-GeF 4 , and the binding energies (6.5 and 6.9 kcal/mol) are 2 to 3 kcal/mol less. Furthermore, the Ge-N potential curves are flatter for the halogenated complexes, exhibit a greater response to dielectric media, and thus these systems are more prone to structural change in condensed-phases. For the 2:1 complexes, experimental and theoretical structure and frequency data are consistent with differences in the (calculated) gas-phase and solid-state structures. For (FCH 2 CN) 2-GeF 4 the calculated gas-phase structure has Ge-N distances about 0.3 Å longer those in the x-ray structure (2.366 Å vs. 2.059 Å (ave)). Also, low-temperature IR spectra of CH 3 CN/GeF 4 , FCH 2 CN/GeF 4, and ClCH 2 CN/GeF 4 thin films are consistent with the presence of 2:1 nitrile:GeF 4 complexes, and the splitting patterns of the GeF-stretching bands (~700 cm-1) match predictions for the corresponding complexes, but are red-shifted relative to the gas-phase predictions, and reflect Ge-N bonds that are compressed in the solid-state, relative to predicted gas-phase structures.
