New homogeneous and alternating Mn(II)-azido 1D systems

• Reaction of sodium azide with manganese(II) and 4-amino-1,2,4-triazol or 3-chloropyridine leads to the 1D systems [Mn(N-3)(2) (4-amtr)(2)](,) (1) or {[Mn(N-3)(2)(3-Clpy)(2)]center dot 1/2(3-Clpy)}(n) (2), respectively. Compound 1 crystallises in the C2/m (monoclinic) group and consists of chains of Mn(II) cations bridged by double mu(1,3)-azido bridges in trans arrangement. Compound 2 crystallises in the I2/a (monoclinic) group and in this case the 1D system shows alternating double mu(1,1) and mu(1,3) bridges. Magnetic properties follow the expected antiferromagnetic (compound 1) and alternating ferro-antiferromagnetic (compound 2) behaviour. (c) 2005 Published by Elsevier Ltd.
