“…53 Immersing the imidazole functionalised cloth into aqueous palladium(II) chloride followed by rinsing in water gave rise to the appearance of palladium and chlorine XPS signals, signifying surface complex formation, Figure 2 and Scheme 1. This was accompanied by the relative attenuation in the 398.7 eV C=N environment, which is consistent with metal complexation to imidazole ligand C=N centres entailing nitrogen lone pair donation to the positively charged metal centre causing a decrease in electron density around the complexing nitrogen atom (increase in N(1s) XPS binding energy 46,58 ), Figure 3.…”

“…All CuLxCI 2 (L = IMDAH, BIMDAH, BTAH, 5MBTAH, PDZ, PYM; x = 2 and 4) complexes were prepared by reacting the appropriate ratio of cupric chloride with ligand in dry ethanolic solution at ambient temperature, according to a previously described procedure [5]. The Cu(BIMDA)2 complex (BIMDA = deprotonated form of BIMDAH) was prepared in 0.1 M NaOH solution as noted previously [5].…”

“…For example, azoles have been used as corrosion inhibitors for metals and alloys [1] and complexes formed between azotes and Cu or Pd metals have been used to model biological structures and in anti-tumor drug therapy [2,3]. The nature of chemical bonding in Cu-azole complexes has been studied by several techniques including Xray photoelectron spectroscopy (XPS) [4,5], Fourier transform infrared spectroscopy (FTIR) [6], and X-ray diffraction [7]. However, at this time relatively little work has appeared on Pd-azole compounds.…”
