The novel ferrocene-based compounds [Fe(eta (5)-C5H4-CH(CH3)OH)(2)] (1), [F
e(eta (5)-C5H3(CH3)COOH)(2)] (2), [Fe(eta (5)-C5H4CH-(CH3)NH(eta (5)-C5H4CH
(CH3))] (3) and the diaminecyclohexane salt [Fe(eta (5)-C5H4 COO)(2)](2-) [
1S,2S-(NH3)(2)C6H10](2+) .2[H2O] (4) have been synthesised and their molecu
lar and supramolecular structures determined by single-crystal X-ray diffra
ction. The hydrogen bonding networks established by the -COOH, CH(CH3)OH, a
nd -COO(-) groups have been studied and the structural parameters compared
with those available for the prototypical dicarboxylic acid [Fe(eta (5)-C5H
4COOH)(2)]. (C) 2001 Elsevier Science B.V. All rights reserved.
