Stereochemistry of [Cu(Tridentate Ligand)2] entities. crystal and molecular structure and electronic properties of [Cu(tedpa)2](PF6)2 (tedpa = N,N,N′N′-tetraethyl pyridinedicarboxamide)

The first metal chelate of un-substituted 2,6-pyridine-dicarboxamide (pdcam): synthesis, molecular and crystal structure, and properties of [CuII(pdc)(pdcam)] · 2H2O (pdc = 2,6-pyridine-dicarboxylato(2−) ligand)

“…In contrast, the neutral R 2 pdcam form prefers to use the O-amide donor to Cu(II) chelation [14]. A similar behaviour is observed for Cu(II) complexes with N,N,N 0 ,N 0 -tetrakis-pdcam derivatives (R 4 pdcam) [15]. The crystal structure of free pdcam is also known [16] but, to the best of our knowledge, no metal-pdcam complex has been studied by X-ray diffraction methods.…”

“…[7,8] Synthesis Physical Methods: Elemental analyses (C,H,N) were carried out with a Perkin-Elmer model 2400 CHN elemental analyzer at the SAIF, Panjab University. Bromide and iodide anions were determined by precipitation as silver salts and sulfur by precipitation as BaSO 4 . IR spectra were recorded as KBr pellets with a PerkinElmer RX-1 FTIR spectrophotometer.…”
