Design, synthesis, structural, and spectra characterize of Metal (II) Formate complexes [M(O2CH)2]•n(Solvent) (M =Mn, Cu)

Abstract

Formate anion is the simplest carboxylate, compared with other carboxylate, it owns more excellent coordination ability. We used M(OAc) 2 ·n H 2 O (M=Mn, Cu) as a raw starting material, hydrothermal synthesis methods assisted by DMF hydrolysis which produced the formyl were adopted to prepare metal(II) formates complexes, Mn(HCOO) 3 ·NH 2 (CH 3 ) 2 (1) and Cu(HCOO) 3 ·H 3 C 2 O 3 (2). The as-prepared products were characterized by elemental analysis, IR spectroscopy, X-ray single-crystal, powder diffraction and thermogravimetric analysis. Structural analysis shows that complex 1 is three-dimensional grid shapes, and complex 2 is a 1D chain structure.
