Abstract:
catena-Poly[[[dichloridoiron(II)]-mu-N,N'-bis(2-pyridylmethylene)benzene-1,4-diamine] methanol disolvate], [FeCl(2)(C(18)H(14)N(4))].2CH(3)OH, forms a one-dimensional coordination polymer. The polymeric chains run parallel to the c axis. O-H...Cl-Fe and C-H...O hydrogen-bonding interactions with methanol solvent molecules stabilize the open supramolecular framework. Each Fe(II) atom adopts an octahedral geometry coordinated by four N atoms from two N,N'-bis(2-pyridylmethylene)benzene-1,4-diamine ligands and completed by two cis Cl atoms. The compound has C(2) (and C(i)) molecular symmetry, which is coincident with the crystallographic twofold symmetry at (0, y, 1/4). The one-dimensional structure is propagated via the crystallographic inversion center located at the benzene ring centroid (0, 1/2, 0).

Metal-Ligand Bonds
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can be...
