| Summary: | The
crystal
and
molecular
structures
of
[bis(5-chloro-2-
methoxybenzoate)tetraaquamanganese(II)], [pentaaqua(5-chloro-2-methoxybenzoato)cobalt(II)] (5-
chloro-2-methoxybenzoate), [pentaaqua(5-chloro-2-methoxybenzoato)nickel(II)] (5-chloro-2-
methoxybenzoate) and [aquabis(5-chloro-2-methoxybenzoate)zinc(II)] monohydrate were determined
by a single-crystal X-ray analysis. Mn(H2O)4L2 (where L = C8H6ClO3) crystallizes in the monoclinic
system, space group P21/c. [Co(H2O)5L]L and [Ni(H2O)5L]L both are isostructural, space group P212121.
The crystals of [Zn(H2O)L2] H2O are monoclinic, space group Pc. Mn(II) ion is positioned at the
crystallographic symmetry center. Mn(II) and Co(II) ions adopt the distorted octahedral coordination
but Zn(II) tetrahedral one.The carboxylate groups in the complexes with M(II) cations function as
monodentate, bidentate and/or free COO-groups. The ligands exist in the crystals as aquaanions. The
complexes of 5-chloro-2-methoxybenzoates with Mn(II), Co(II) and Zn(II) form bilayer structure.
