In the title compound, 2[Fe(C5H5)(C6H5O2)].C6H12N2, the molecular component
s are linked into finite three-component aggregates by strong O-H . . . N h
ydrogen bonds [O . . . N 2.578 (4) and 2.604 (5) Angstrom; O-H . . . N 170
(5) and 174 (6)degrees]; these aggregates are further linked by C-H . . . O
hydrogen bonds [C . . . O 3.327 (5)-3.401 (5) Angstrom; C-H . . . O 149-15
7 degrees] into continuous sheets in the form of (6,3) nets.
