Synthesis, crystal structure and magnetism of a one-dimensional MnII chain with a single μ1,3-azido as bridge ligand

A new 1-D MnII chain, [Mn( 1,3-N3)(phenCl)2]n (ClO4)n (phenCl=2-chloro-1,10-phenanthroline), was synthesized with single 1,3-azido as bridge and 2-chloro-1,10-phenanthroline as coligand, and its crystal structure determined by X-ray crystallography. In the complex, MnII is located in a distorted octahedral geometry, and azide is an end-end bridge, linking two MnII ions with separation of 5.7356(10) angstrom, forming a 1-D chain. In the crystal, there are two kinds of - stacking between adjacent chains. The fitting of the variable-temperature (2.00320K) magnetic susceptibilities gave an anti-ferromagnetic interaction of J=5.99cm1 (), among the stronger magnetic interaction in MnII complexes with azido as single end-end bridge. Reported experimental results do not confirm clearly the magneto-structural correlations revealed by theoretical calculations.
