Nw. Alcock et al., A CIS-OCTAHEDRAL DICHLORO COMPLEX OF FE-III WITH A TETRADENTATE DIPYRIDYL-DIAMINO LIGAND, Acta crystallographica. Section C, Crystal structure communications, 53, 1997, pp. 1385-1387
In [N,N'-bis(2-pyridylmethyl)-1, 3-propanediamine-N,N',N '',N''']dichl
oroiron(III) perchlorate, [FeCl2(C15H20N4)]ClO4, the linear tetradenta
te Ligand adopts the cis-beta configuration which provides a favourabl
e geometry for the six-membered chelate ring. The Fe-N distances show
lengthening from the trans influence of the chloride ligands, with Fe-
N-py values of 2.152 (3) and 2.179 (3) Angstrom, and Fe-N-amine distan
ces of 2.141 (4) and 2.178 (4) Angstrom.
