2-Chloroquinoline iodomonochloride

Abstract

CgH6CIzlN, monoclinic, space group P2~/c; a=8.297 (1), b= 15.257 (8), c=8-831 (4) ,~, ,8=110.38 (3)°; Z=4, Dm=2"068, Dx=2"066 g cm -3. The structure was refined to an R of 0.03. The complex is planar with a linear N... I-C1 grouping extending along the expected orientation of the N atom lone pair.

Structural and Photophysical Properties of Lanthanide Nitrate 1:1 Complexes with planar tridentate nitrogen ligands analogous to 2,2′:6′,2′‐terpyridine

“…All coordinates of H-atoms were calculated. For 4, the absolute configuration has been established by refinement of the enantiomorph-polarity parameter [25] (x = -0.01(2)). The structure of the complex 8 shows a slight disorder on the three terminal C-atoms of one of the octyl chains.…”

Iodine and Halogen Bonding

“…These dimers interact with each other to give infinite chains (Fig. 8.13, left) where the chlorine and iodine atoms of any ClI unit form a bifurcated HB with a quinoline proton [65]. An interesting structure was reported by A.I.…”

Reactions Between Chalcogen Donors and Dihalogens/Interalogens: Typology of Products and Their Characterization by FT‐Raman Spectroscopy

“…adducts with both - and -donors show one main peak in their FT-Raman spectra in the range 190–140 cm −1 [16, 59, 60, 62–67, 81] at a lower frequency with respect to solid [216 cm −1 , d (I−Br) = 2.521(4) Å] [98], and it is assignable to a stretching vibration of the E−I−Br three-body system having a major contribution from the ν (I−Br) vibration [63]. adducts (only four out of seven are both structurally and vibrationally characterized) [60, 67, 68] generally show in their FT-Raman spectra two main peaks: one in the range 240–180 cm −1 presumably due to the antisymmetric ( ν 3 ) stretching vibration of the E−I−Cl three body-system ( = , ), and the other at about 130 cm −1 due to the symmetric ( ν 1 ) stretching vibration (solid is characterized by a single peak at 283 cm −1 in its FT-Raman spectrum with a d (I−Cl) = 2.446(6) Å) [99]. Interestingly, by considering the Δ d (I−Y) parameter ( = , , ), a linear correlation appears also to exist between Δ d (I−Br) and ν (I−Br) for adducts, and between Δ d (I−Cl) and the ν (E−I−Cl) stretching mode corresponding to the ν antisym in symmetric three-body systems, for adducts (Figure 8).…”
