Two novel trinuclear cluster-based coordination polymers with 2,6-Di-imidazol-1-yl-pyridine: solvothermal syntheses, crystal structures, properties and Hirshfeld surface analysis
<p>Two novel trinuclear cluster-based coordination polymers {[M<sub>3</sub>(dip)(AcO)<sub>6</sub>]·(X)}<sub>n</sub> (<b>1</b>, M = Cu, X = CH<sub>3</sub>OH; <b>2</b>, M = Co, X = 2H<sub>2</sub>O) (dip is 2,6-Di-imidazol-1-yl-pyridine), have been synthesised and structurally determined by single crystal X-ray diffraction, element analysis. Crystallographic unit of <b>1</b> consists of three Cu(II), six acetic ions, one dip ligand and one methanol molecule, which formed 1D chain through acetic bridges. The 1D chain further constructed 2-D network through dip ligand bridge which formed 3-D network through π···π interaction. Crystallographic unit of <b>2</b> consists of three Co(II), six acetic ions, one dip ligand and two water molecules. The trinuclear unit further formed a dimmer through dip ligand bridge which constructed 1-D through dip ligand bridge. The 1D chain further constructed 2-D network through π···π interaction. IR and UV–vis spectrum properties of <b>1</b> and <b>2</b> were studied. In addition, Hirshfeld surface analysis was also studied for <b>1</b>.</p
