Abstract
We have examined the 155Gd Mössbauer spectra at 12 K for 25 complexes having different coordination numbers and different ratios of coordinating oxygen to nitrogen atoms. The isomer shift decreases in the order: GdO10≈GdO9>GdN2O7≥GdO8≈GdN6O2≥GdO7≥GdO6>GdN8≈GdN9. The s electron density at the nucleus is larger as the coordination number decreases and as the coordinating atoms change from oxygen to nitrogen, suggesting the covalency in the bonding.
