Abstract
The crystal structures of
[Fe(aha)3]·1.5H2O
and
[Fe(bha)3]·3H2O
(ahaH = acetohydroxamic acid, bhaH = benzohydroxamic acid) have
been determined.
[Fe(aha)3]·1.5H2O
crystallizes in the monoclinic space group
P21/ c
(a 19.169(4), b 8.5738(3),
c 12.257(3) Å, α = γ =
90°, β 92.255(4)°). The two isomeric forms
(fac and mer) cocrystallize. The
structure of
[Fe(bha)3]·3H2O
is as reported previously (monoclinic,
P21/n,
a 12.9998(16), b 13.2196(16),
c 14.1154(17) Å, α = γ =
90°, β 90.809(2)°) but with improved refinement giving an
R value of 0.03 compared to 0.12. In each complex the
geometry of the Fe centre is octahedral but with significant distortion.
