| Popis: |
Crystals of the title compound are monoclinic, space group C2/c, with dimensions a= 26·04, b= 9·24, c= 9·45 A, β= 94·25°. The structure was solved by Fourier methods and the molecular parameters refined by full-matrix least-squares calculations to R 0·102 for 1681 independent reflexions. The copper atom lies on the crystallographic centre of symmetry with Cu–O(acetate) 1·976 and Cu–N 2·052 A. Distorted octahedral co-ordination around the copper atom is completed by bridging water molecules, Cu–O(water) 2·595 A, which are shared by adjacent octahedra. The remaining water molecules, which are not co-ordinated to the copper atom, form a hydrogen-bonded chain. The single-crystal e.s.r. spectrum and powder magnetic susceptibilities over the temperature range 80–300 K are discussed in terms of the structure. The magnetic susceptibilities of the aniline and p-toluidine adducts of Cu(BuO2)2 and Cu(PrO2)2 are also reported and discussed. |
