Synthesis, crystal structures and magnetic properties of a coordination polymer containing the [Mn5(μ1,1-N3)8(N3)2(bpd)5(H2O)2] repeat cluster units (bpd = 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene)

A novel 1-D ferromagnetic compound based on manganese(II) and azide with formula [Mn5(μ1,1-N3)8(N3)2(bpd)5 (H2O)2] · bpd · H2O (1) (bpd = 1,4-bis(4-pyridyl)-2,3-diaza-1,3-butadiene) was synthesized and structurally and magnetically characterized. Single-crystal X-ray diffraction shows that 1 consists of a one-dimensional convalent constructed by linear Mn5II subunits, in which each MII ion is coordinated in a distorted octahedral geometry. Magnetic measurements have been performed for the compound, showing a moderate ferromagnetic coupling.
