The title complexes were modeled using the semiempirical MOPAC and the newly developed SPARKLE paramerters of the lanthanides. The calculated bond dis tances and angles agreed well with those found from crystal struct...
Theoretical investigation on the structures of the octacoordinated [Nd(CO3)4]5-and the nonacoordinated [Nd(CO3)4.OH2]5-complexes, using the SPARKLE parameters of the lanthanides within MOPAC, revealed that they posses...
1 Results We have recently reported the successful use of some new ionophores in construction of PVC-based membrane selective sensors for Fe3+,Ni2+,Co2+,Hg2+ and Cd2+ ions by some Schiff base ligands. Schiff bases are...

Three diamino-substituted nitrogen-heterocyclic NLO chromophores were synthesized via a facile procedure. Compared to their benzene analogues, the thermal stability and transparency of synthesized chromophores are imp...
