Schiff bases are a kind of important ligands in coor
dination chemistry [1–3]. In recent years, metal com
plexes of Schiff bases have attracted dramatically at
tention due to their versatile biological activity, such as
antifungal, antibacterial and antitumor [4–6]. It has
been shown that the Schiff base complexes derived
from salicylaldehyde and its derivatives with primary
amines, bearing the N
or NSO donor
sets, have interesting biological activity [7–10]. In ad
dition, the molecular design of extended structures
starting from molecular precursors is of great interest.
A preferred way to construct such materials is to use
ionic building blocks in which one unit contains a poten
tial bridging ligand and another contains a potential co
ordination site . In the present paper, the prepara
tion, characterization and antimicrobial activity of a new
hetero trinuclear manganese(III)iron(II) complex,
where ClSalen is the dianionic form of
ClSalen), is reported.

temperature for 1 h. To the mixture was added
O (0.362 g, 1 mmol) with stirring for
30 min. Then, the methanol solution of the above
brown solution was carefully layered on the top of an
aqueous solution (5 mL) of Na

crystals of the complex, suitable for single crystal
Xray diffraction, were formed after a few days. The
yield was 413 mg.

A new hetero trinuclear manganese(III)iron(II) complex, [Mn(ClSalen)(H
O, where ClSalen is the dianionic form of
has been prepared and characterized by elemental analyses, IR, and single crystal Xray crystallographic de
termination (CIF file CCDC no. 1024666). The crystal of the complex is orthorhombic: space group
= 0.1406. The
Schiff base ligand coordinates to the Mn atom through two phenolate O and two imine N atoms. Each
Mn atom in the complex is in octahedral coordination, with the equatorial donor atoms come from the Schiff
base ligand, and with the axial donor atoms come from a water O atom and a cyanide N atom. The effects of
the complex on the antimicrobial activity against
