摘要：

Two new cobalt complexes: Co-3(NO2)(4)(NH2CH2CH2O)(4). H2O (1) and (NH2(C6H11)(2))(3) [Co-2(NO2)(8)OH]. 3H(2)O (2) and the compound (NH2(C6H11)(2))NO2 (3) were synthesised and their structures have been determined using single-crystal X-ray diffraction. Compound 1 consists of two centrosymmetrical trinuclear complexes and a water molecule of crystallization. Ligands coordinated to Co atoms are nitro and aminoethanolato groups. Structure 2 is built up of biscyclohexylammonium cations, dinuclear anions with hydroxo and nitro groups coordinated to Co atoms and water molecules. The coordination of Co atoms in both structures is roughly octahedral. (C) 1999 Elsevier Science Ltd. All rights reserved.
