  We present the hydrothermal synthesis, as well as structural and chemical
analysis of single crystals on the compounds EuCu$_{3}$(OH)$_{6}$Cl$_{3}$,
Zn$_{x}$Cu$_{4-x}$(OH)$_{6}$(NO$_{3}$)$_{2}$ and haydeeite,
MgCu$_{3}$(OH)$_{6}$Cl$_{2}$ all arising from the atacamite family. Magnetic
and specific-heat measurements down to 1.8 K are carried out for these systems.
EuCu$_{3}$(OH)$_{6}$Cl$_{3}$ has a frustrated antiferromagnetic Cu$^{2+}$
ground state with order at 15 K, a strong anisotropy and increased
magnetization from Van Vleck paramagnetic Eu$^{3+}$ contributions.
ZnCu$_{3}$(OH)$_{6}$(NO$_{3}$)$_{2}$ reveals antiferromagnetic order at 9 K and
measurements on haydeeite single crystals confirm the ferromagnetic order at
4.2 K with the easy axis within the kagome plane. These results prove that the
atacamite family presents a broad class of materials with interesting magnetic
ground states.
