| Abstract: | The new monomeric complexes of M(MPA)2(H2O)2] (1: M=Co; 2: M=Ni) (HMPA=5-methyl-1H-pyrazole-3-carboxylic acid) were synthesized by the reaction of 5-methyl-1H-pyrazole-3-carboxylic acid with CoCl2·6H2O and Ni(NO3)2·6H2O, respectively. The compounds were characterized by elemental analysis, IR spectra, single crystal X-ray diffraction. The structural parameters of 1 and 2 were analyzed as follows: 1, Hexagonal, R3c, a=1.48394(4) nm, b=1.483 94(4) nm, c=3.207 66(6) nm, V=6.1172(3) nm3, Z=18; 2, Hexagonal, R3c, a=1.466 53(14) nm, b=1.466 53(14) nm, c=3.243 0(6) nm, V=6.040 3(14) nm3, Z=18. Metal ions have all octahedral geometry coordinated by two nitrogen atoms and two oxygen atoms from two MPA- ligands, two oxygen atoms from two H2O molecules. In both complexes, the independent components M(MPA)2(H2O)2] are connected by intermolecular hydrogen bonds to form a three-dimensional architecture with hexagonal channels. Thermogravimetric analyses show that 1 and 2 have higher thermal stability. In addition, the luminescent properties and electrochemical properties of complexes 1 and 2 have also been investigated. |
