A new 1-D MnIIchain, [Mn(μ1,3-N3)(phenCl)2]n(ClO4)n(phenCl = 2-chloro-1,10-phenanthroline), was synthesized with singleμ1,3-azido as bridge and 2-chloro-1,10-phenanthroline as coligand, and its crystal structure determined by X-ray crystallography. In the complex, MnIIis located in a distorted octahedral geometry, and azide is an end-end bridge, linking two MnIIions with separation of 5.7356(10) Å, forming a 1-D chain. In the crystal, there are two kinds of π-π stacking between adjacent chains. The fitting of the variable-temperature (2.00–320 K) magnetic susceptibilities gave an anti-ferromagnetic interaction ofJ = –5.99 cm–1(), among the stronger magnetic interaction in MnIIcomplexes with azido as single end-end bridge. Reported experimental results do not confirm clearly the magneto-structural correlations revealed by theoretical calculations. [ABSTRACT FROM AUTHOR]
