Abstract

X-ray diffraction analysis of Co(HNta) · 4H2O (I) (H3Nta = N(CH2COOH)3) revealed that its crystals are isostructural to a Zn analog and built from [Co(HNta)(H2O)3] complex molecules and crystallization water. The octahedral coordination of the Co atom includes two O atoms and an N atom provided by the chelating tridentate HNta2–ligand (average Co–O (Nta) 2.055 Å and Co–N 2.205 Å) and three O atoms of water molecules on the shared face (average Co–O(w) 2.105 Å).
