Microwave-assisted synthesis, structure and properties of a co-crystal compound with 2-ethoxy-6-methyliminomethyl-phenol

A new co-crystal complex [Ni-7(emmp)(6)(CH3O)(2)(OH)(4)][Ni(emmp)(2)]center dot(ClO4)(2) (1, Hemmp is 2-ethoxy-6-methyliminomethyl-phenol) has been synthesised by microwave-assisted method. Complex 1 was characterised by IR spectroscopy, elemental analysis, Raman spectroscopy and X-ray single-crystal diffraction. The complex consists of a heptanuclear cation cluster [Ni-7(emmp)(6)(CH3O)(2)(OH)(4)](2+), a mononuclear complex [Ni(emmp)(2)] and two counteranions. Complex 1 displays the contents of antiferromagnetic and ferromagnetic properties.
