Nickel(II) and cobalt(II) chelates with products of condensation of 1,8-diaminonaphthalene and salycylaldehyde
摘要:
Six Ni(II) and Co(II) chelates were synthesized from different reagents (Ni(II), Co(II) chlorides and 1,8-diaminonaphthalene or the products of a single or double condensation of the latter with salicylaldehyde) and identified and characterized by elemental analysis, powder X-ray diffraction, thermogravimetry, and conductivity methods. The ligand coordination mode and the spatial structure of the complexes were established from the magnetochemisty and spectroscopy (IR, diffuse reflection) data. The dimeric structure of one of the complexes formed due to the chloride bridges was confirmed by EXAFS method.
selective fluorimetric optode for determination of trace amounts of Ho(3+) ions was prepared. The sensing system was prepared by incorporating of N,N-bis(salicylidene)-naphthylene-1,8-diamine (L) as a neutral Ho(3+)-selective fluoroionophore, in a plasticized PVC membrane containing sodium tetraphenyl borate as a lipophilic anionic additive. The response of the sensor is based on the strong fluorescence

Two new bimetallic complexes NiZnC22H14N4S2O2PPh3 and NiZnC26H16N4S2O2PPh3 has been synthesized and characterized using various spectral techniques like FT-IR, electronic, EDAX and SEM images. The synthesized complexes has been screened for the in-vitro antimicrobial activity against various test organisms. The complexes showed moderate to good potency against bacterial strains developing a productive
