Microwave Assisted Synthesis, and Structure of a Co-Crystal Nickel Complex with 2-ethoxy-6-methyliminomethyl-phenol

Abstract

A new co-crystal complex [Ni7(emmp)6(OH)6][Ni(emmp)2]·(CH3CN)2·(ClO4)2 (1, Hemmp is 2-ethoxy-6-methyliminom-ethyl-phenol) has been synthesized by microwave-assist solvothermal method. Complex 1 was characterized by IR spectroscopy, elemental analysis, and X-ray single-crystal diffraction. The 1 was consist of a nano-bowl-like heptanuclear cation cluster [Ni7(emmp)6(OH)6]2+, two counterion ClO4−, one neutral mononuclear complex [Ni(emmp)2] and two acetonitrile molecules. The five part of 1 constructed a whole through M···H interaction, O–H···N hydrogen bonds and C–H···O hydrogen bonds.
