HYDROGEN-BONDED ADDUCTS OF FERROCENE-1,1'-DIYLBIS(DIPHENYLMETHANOL) WITH NITROGENOUS BASES - CRYSTAL AND MOLECULAR-STRUCTURE OF THE 2 1 ADDUCT WITH HEXAMETHYLENETETRAMINE/

Ferrocene-1,1'-diylbis(diphenylmethanol) [Fe(C(5)H(4)CPh(2)OH)(2)] for ms hydrogen-bonded host-guest adducts with nitrogenous bases. A 2:1 ad duct is formed with hexamethylenetetramine, [(CH2)(6)N-4], 1:1 adducts with 1,4-dimethylpiperazine and 1,4-diazabicyclo [2.2.2]octane and a 1:2 adduct with 3-pyridylferrocene. The crystal structure of the hexam ethylenetetramine adduct has been determined. The structural unit cont ains two molecules of the host ferrocenediol and one molecule of the g uest; the diol forms both intramolecular O-H ... O and intermolecular O-H ... N hydrogen bonds, but two of the four nitrogen atoms in the [( CH2)(6)N-4] guest molecules play no part in the hydrogen bonding.
