dc.description.abstractA new coordination compound, namely [LaL2(NO3)(H2O)(2)]center dot 5H(2)O (1), has successfully been synthesized from La(NO3)(3)center dot 6H(2)O, 2-pyridinecarboxaldehyde isonicotinoylhydrazone (HL) and NaOH, as a deprotonated agent, in the CH3OH medium under mild solvothermal conditions at 120 degrees C. Both HL and 1 were characterized by FTIR spectroscopy and elemental analysis. Complex 1 was also studied by the simultaneous TG-DSC, powder and single crystal X-ray diffraction analyses. According to the single crystal diffraction analysis, the lanthanum (III) ion adopts a deca-coordinated mode, and five lattice water molecules exist in the asymmetric unit. The crystal structure of 1 is mainly stabilized by strong O-H center dot center dot center dot N and O-H center dot center dot center dot O and weak pi/pi and C-H center dot center dot center dot p interactions. As a result of hydrogen bonding, a 3D supramolecular structure is formed with a binodal (3,6)-connected network with a 3,6T49 topology having point symbol of {4 center dot 6(2)}{4(7)center dot 6(5)center dot 8(3)}. As evidenced from the Hirshfeld surface analysis of [LaL2(NO3)(H2O)(2)], intermolecular H center dot center dot center dot H (40.1%), H center dot center dot center dot C (15.4%), H center dot center dot center dot N (12.2%) and H center dot center dot center dot O (20.3%) contacts occupy an overwhelming majority of a molecular surface of the complex molecule. Highly favoured intermolecular C center dot center dot center dot C (6.5%) and C center dot center dot center dot N (4.0%) contacts also play a vital role in the supramolecular structure of complex. Upon heating, complex 1 decomposes in few steps, consistently losing lattice water molecules, coordinated water molecules followed by the decomposition of organic ligands, yielding La(NO3)(3) followed by the formation of a final residue La2O3.
