  We report the controlled growth of single crystals of intercalated layered
Lu$ _{1+n} $Fe$ _{2+n} $O$ _{4+3n-\delta} $ ($ n $=1,2) with different oxygen
stoichiometries ${\delta}$. For the first time crystals sufficiently
stoichiometric to exhibit superstructure reflections in X-ray diffraction
attributable to charge ordering were obtained. The estimated correlation
lengths tend to be smaller than for not intercalated LuFe$ _2 $O$ _4$. For Lu$
_2 $Fe$ _3 $O$ _7 $, two different superstructures were observed, one an
incommensurate zigzag pattern similar to previous observations by electron
diffraction, the other an apparently commensurate pattern with
($\frac{1}{3}\frac{1}{3}0$) propagation. Implications for the possible charge
order in the bilayers are discussed. Magnetization measurements suggest reduced
magnetic correlations and the absence of an antiferromagnetic phase.
