Crystal Structure of the 1:1 Addition Compound Iodoform-1,4-Dioxan.

Charge-transfer complexes of iodoform with 1,4-dioxane, -dithiane, and -diselenane: Theoretical electron density and energy decomposition analysis

“…The iodoform octasulfur (CHI 3 Á Á Á S 8 ) is an example of such type of charge-transfer complex and the nature of charge-transfer (IÁ Á ÁS) interaction has been investigated by experimental charge density analysis based on its crystal structure [33]. Besides iodoform octasulfur, the charge-transfer complexes of iodoform with dioxane, dithiane, and diselenane were also found in their crystal forms [34][35][36]. Despite the fact that these CT complexes are very typical and representative, the CT interactions are not fully understood in terms of their strength, geometrical preference, and fundamental physical nature.…”

Three-dimensional linkage by electron donor-acceptor interactions: complexes of organic ammonium halides with triiodomethane

“…It is known that triiodomethane forms solid chargetransfer complexes with n-donors such as 1,4-dioxane, 1,4-dithiane, 1,4-diselenane, quinoline, and other neutral mojecules. [5][6][7][8] In the l,4-dithiane-HCI3 complex, chains of alternating donor and acceptor molecules have been found by X-ray analysis.6 78From l27I NQR measurements it has been suggested that sp3d-hybridized iodine atoms are present.9 IR and Raman spectra of the complexes have been examined. 10 Less work has been dope on complexes between halides and triiodomethape.…”
