Crystal and molecular structure of aquo(dihydrogen ethylenediaminetetra-acetato)copper(II)

Abstract

The crystal structure of aquo(dihydrogen ethylenediaminetetra-acetato)copper(II) has been determined by X-ray diffraction methods using counter data. Refinement, to R 0·037, was carried out by a least-square procedure. There are four molecules in the monoclinic unit cell, space group P21/c, with dimensions a= 11·641, b= 7·005, c= 16·576 Å, β= 91·5°. The dihydrogen ethylenediaminetetra-acetate ion acts as a quinquedentate ligand, one acetate grouping remaining free, and the six-co-ordination about copper atom is completed by a water molecule. The copper atom environment is a tetragonally elongated octahedron with four coplanar bonds, Cu–N(2) 2·066, Cu–OH2 1·978, Cu–O(7) 1·970, Cu–O(8) 1·929 Å, and two longer bonds Cu–N(1) 2·291 and Cu–O(9) 2·467 Å[σ(Cu–N,O) 0·002–0·003 Å].
