Abstract

The crystal of [Co(H₂O)₆]·(Hnip) ₂·(H₂nip)₂·(DMA) ₂·(H₂O)₈ has been cultured using direct method and characterized by X-ray single crystal diffractometry, elemental analysis and FTIR spectroscopy. It crystallizes in triclinic system, P-1 space group with the cell parameters of a=0.7012(l) nm, b=1.1378(2) nm, c=1.6612(3) nm, α= 84.92(3)°, β=85.19(3)°, γ=85.91(3)°, V=1.3128(5) nm³, Z=1, D_c=1.573 g·cm^-3. Final R indices [I>2σ(I)] are: R₁=0.0279, wR ₂=0.0765 while R indices for all data are: R₁ =0.0327, wR₂=0.0806. The Co coordination octahedra are each surrounded by two Hnip, two H₂nip, two DMA and eight water molecules that are linked by hydrogen bonds and π-π stacking interactions. Thermal analyses of DSC and TG-DTG have been performed on the complex to predict its thermal decomposition mechanism and determine the most probable kinetic model function using Kissinger, Ozawa, integral and differential methods.
