  We report the synthesis, crystal structure and characterization by means of
single crystal x-ray diffraction, neutron powder diffraction, magnetic, thermal
and transport measurements of the new heavy fermion compounds
Ce$_{2}$MAl$_{7}$Ge$_{4}$ (M = Co, Ir, Ni, Pd). These compounds crystallize in
a noncentrosymmetic tetragonal space group P\={4}2$_{1}$m, consisting of layers
of square nets of Ce atoms separated by Ge-Al and M-Al-Ge blocks.
Ce$_{2}$CoAl$_{7}$Ge$_{4}$, Ce$_{2}$IrAl$_{7}$Ge$_{4}$ and
Ce$_{2}$NiAl$_{7}$Ge$_{4}$ order magnetically behavior below $T_{M}=$ 1.8, 1.6,
and 0.8 K, respectively. There is no evidence of magnetic ordering in
Ce$_{2}$PdAl$_{7}$Ge$_{4}$ down to 0.4 K. The small amount of entropy released
in the magnetic state of Ce$_{2}$MAl$_{7}$Ge$_{4}$ (M = Co, Ir, Ni) and the
reduced specific heat jump at $T_M$ suggest a strong Kondo interaction in these
materials. Ce$_{2}$PdAl$_{7}$Ge$_{4}$ shows non-Fermi liquid behavior, possibly
due to the presence of a nearby quantum critical point.
