摘要：

The crystal and molecular structure of [(Cu(pmdien)F(H-2,O)}(2)],I[BF4](2),I, 1 (pmdien = N,N,N',N ",N "-pentamethyldiethylenetriamine) has been determined. The cation exists in the solid state as a unique dimer, held together by O-H ... F hydrogen-bonding interactions [O ... F 2.567(2), O-H 0.83(3), F ... H 1.74(3) Angstrom, F ... H-O 178.5(23)degrees]. The O ... F separation is the shortest ligand fluoride-ligand water hydrogen-bonding interaction in any copper(II) complex. The copper atom is five-co-ordinate and has a square-based pyramidal geometry comprising equatorially located pmdien (mean Cu-N 2.052 Angstrom), and fluoride [Cu-F 1.888(1) Angstrom] and axially located water [Cu-O 2.211(1) Angstrom].
