“…47 A similar result has been reported for mesomorphic gold(I) and silver(I) ionic isocyanide complexes. 46 It is interesting to compare the thermal behavior of the neutral 2-4 complexes, which are not liquid crystals, with that of the mesomorphic cationic derivatives 5-7. The observed variation in thermal properties is as follows: The melting points decrease in the order neutral complexes > cationic derivatives.…”

1,1'-Difunctionalised ferrocene derivatives have been studied, which contain groups suitable for chemisorption on gold substrates, namely -NC, -PR(2) as well as a range of sulfur-containing units like -NCS, -SR, and thienyl. Thin films on gold have been fabricated from solution with most of these adsorbate species. Film thickness, composition and structure were investigated primarily by X-ray photoelectron and near-edge X-ray absorption fine-structure spectroscopy. The quality of self-assembled monolayers fabricated from 1,1'-diisocyanoferrocene (1) and 1,1'-diisothiocyanatoferrocene (2) turned out to be superior to that of films based on the other adsorbate species investigated. In addition to the surface coordination behaviour of 1 towards gold substrates, relevant aspects of the molecular coordination chemistry of 1 have also been addressed, including the synthesis and characterisation of [(mu-1){Cr(CO)(5)}(2)], [Ag(2)(mu-1)(2)](NO(3))(2) x H(2)O and [(mu-1)(AuCl)(2)]. The crystal structure of the gold complex is governed by aurophilic interactions and can be taken as a model for the arrangement of 1 in self-assembled monolayers on gold.

“…Although there are many reports on argentomesogens in the literature, 15 mesomorphic complexes based on isocyanide silver derivatives are scarce. 16,17 Here we report 4-isocyanoacetanilide silver complexes [AgX(CNR)] (X = NO 3ˉ (2), CF 3 SO 3ˉ (3)) and [Ag(CNR) 2 ]X (X = NO 3ˉ (4), CF 3 SO 3ˉ (5), BF 4ˉ (6)). Their X-ray diffraction structures show in all cases the formation of layered supramolecular structures supported by hydrogen bonding, and Ag-O interactions involving mainly the amide group and the anionic ligand present in the complexes.…”
