A Ferrocenyl Amino Substituted Stannylene as an Intramolecular Fe→Sn Lewis Adduct

Abstract

The acyclic ferrocenyl amino substituted stannylene Sn[N(Fc)SiMe 3 ] 2 1 was synthesized from tin(II) chloride and in situ formed LiN(Fc)(SiMe 3 ). The molecular structure of 1 in the solid state shows two short intramolecular Fe···Sn contacts suggesting electron * Dr.C. Förster

d–d Dative Bonding Between Iron and the Alkaline‐Earth Metals Calcium, Strontium, and Barium

“…[5] In contrast, complexes of the main-group metals are hardly known and Fe•••metal interactions are only rarely and, as expected for weak bonding,often carefully discussed. [6][7][8][9][10][11][12][13][14][15] This holds especially for Fe interactions with s-block metals. [9][10][11][12][13] TheW agner group has reported ab orate-bridged ferrocene (II), which is ahighly efficient Li + scavenger likely because of Fe•••Li + interactions.…”
