“…is, like that in[I 4 Br 4 ] 2À at 2.7303(9) ,o nt he short end of those observed in [I 8 ] 2À ions (average2 .772 ). [13b] There are no previously-reported non-classical iodine-chlorine interhalides containing ICl 2 À units;h owever,t here are four structurally-characterized examples of chloride ions coordinated to I 2 .I n[ Cl(I 2 ) 4 ] À ,i nw hich each I 2 is coordinated by one chloride, the IÀId istances are even shortera t2 .699(1)and 2.705(2) .I nt he other three examples, [I 2 Cl 2 ] 2À ,[ I 2 Cl À ] n and [Cl 2 I 14 ] 2À ,e ach I 2 is coordinated linearly by two chlorides and the IÀId istances range from 2.71-2.74 which is similart o Scheme5.Formation of [ICl 4 ] À from the trihalide [ICl 2 ] À .…”

“…[8] Intermolecular interactions and soft I-Cl-I angles are believed to be responsible for the non-tetrahedral shape. Therea re also two examples of infinite networks involving alternating chloride and diiodine:[ I 2 Cl À ] n (V)h as an infinite chain of alternating halide and dihalogen, [9] whereas [ClI 7 À ] n (VIII)c onsists of a2 Dn etwork in which each chlorideisc oordinated to five I 2 in as quare pyramidal arrangement such that four I 2 are bridging to another chloride and one I 2 is terminal. Additional I 2 links the 2D network through I atomst of orm am ore extensive 3D polyhalide network.…”

Polyhalogen‐ und Polyinterhalogen‐Anionen von Fluor bis Iod

“…[140] Polyinterhalogen-Anionen vonC l À mit I 2 : [C 12 H 9 N 2 ] 2 [I 2 Cl][ICl 2 ]( [C 12 H 9 N 2 ] = 1,10-Phenanthrolin-1ium, phenH + )e nthält das [I 2 Cl] À -Anion. [132] Interessanterweise enthält die Verbindung neben diesem nichtklassischen Anion auch das klassische Polyinterhalogen-Anion [ICl 2 ] À . Die [I 2 Cl] À -Anionen bilden periodische Ketten mit I-I-Bindungslängen von 273.7(1) pm, ähnlich der Länge in elementarem Iod (271.5(6) pm [141] ).…”
