An Interesting Conversion Route of Mononuclear Zinc Complex to Zinc Mixed Carboxylate Coordination Polymer
A complex [Zn(bpy)(acr)<sub>2</sub>]·H<sub>2</sub>O (<b>1</b>) was converted in a DMF medium (DMF = <i>N,N</i>′-dimethylformamide) into a coordination polymer [Zn(bpy)(acr)(HCOO)]<sub>n</sub> (<b>1a</b>) (bpy = 2,2′-bipyridine,...

| description | A complex [Zn(bpy)(acr)<sub>2</sub>]·H<sub>2</sub>O (<b>1</b>) was converted in a DMF medium (DMF = <i>N,N</i>′-dimethylformamide) into a coordination polymer [Zn(bpy)(acr)(HCOO)]<sub>n</sub> (<b>1a</b>) (bpy = 2,2′-bipyridine, and Hacr = acrylic acid), and the species was fully characterized through a single crystal X-ray diffraction. Additional data were obtained by IR and thermogravimetric analysis. Complex (<b>1a</b>) crystalized the coordination polymer in the space group <i>Pca</i>2<sub>1</sub> of an orthorhombic system. Structural characterization revealed that Zn(II) adopted a square pyramidal stereochemistry generated by bpy molecules, coordinated by chelate, acrylate, and formate ions as unidentate and bridged, respectively. The presence of both the formate and the acrylate with different coordination modes generated two bands in ranges that were characteristic for the carboxylate vibration modes. Thermal decomposition occurs in two complex steps: it first happens via a bpy release, which is followed by an overlapped process that is associated with acrylate and formate decomposition. The obtained complex is of present interest due to the presence of two different carboxylates in its composition and situation, which is rarely reported in the literature. |
