Synthesis, characterization and weak ferromagnetic coupling in [Cu2(μ3-CO3)(SCN)2(py)4]n

The crystal structure of a novel [Cu2(μ3-CO3)(SCN)2(py)4]n complex has been determined. It comprises of [CuCO3Cu]n infinite chains, running along the a-axis, and is in this aspect similar to the previously described [Cu(CO3)(4-aminopyridine)2]·H2O complex. The FTIR spectrum of [Cu2(μ3-CO3)(SCN)2(py)...

Description
Summary:The crystal structure of a novel [Cu2(μ3-CO3)(SCN)2(py)4]n complex has been determined. It comprises of [CuCO3Cu]n infinite chains, running along the a-axis, and is in this aspect similar to the previously described [Cu(CO3)(4-aminopyridine)2]·H2O complex. The FTIR spectrum of [Cu2(μ3-CO3)(SCN)2(py)4]n has been recorded and analyzed. A CuCO3Cu intrachain coupling between Cu(II) atoms has been found to be responsible for the weak ferromagnetic properties of [Cu2(μ3-CO3)(SCN)2(py)4]n. A CuCO3Cu intrachain coupling between Cu(II) atoms has been found to be responsible for the weak ferromagnetic properties of [Cu2(μ3-CO3)(SCN)2(py)4]n. [Display omitted] •[Cu2(μ3-CO3)(SCN)2(py)4]n cannot be formed without atmospheric CO2 and O2.•[Cu2(μ3-CO3)(SCN)2(py)4]n possesses low-temperature weak ferromagnetism.•Cu(II)-Cu(II) spin coupling causes the ferromagnetism in [Cu2(μ3-CO3)(SCN)2(py)4]n.
