A new two-dimensional manganese(II)–azide polymer. Synthesis, structure and magnetic properties of [{Mn(minc)2(N3)2}n] (minc = methyl isonicotinate) †

A new two-dimensional manganese compound showing µ1,3-azido bridges has been synthesized and structurally characterised. The complex [{Mn(minc)2(N3)2}n], where minc corresponds to methyl isonicotinate, crystallises in the monoclinic system, space group P21/c, a = 12.424(5), b = 8.496(3), c = 8.399(4) Å, β = 96.41(3)° and Z = 2. Magnetic measurements show behaviour typical of a two-dimensional Heisenberg antiferromagnet with J = –2.24(2) cm–1. Low-temperature properties are discussed in comparison with those of some molecular magnets of the [{MnL2(N3)2}n] series.
