摘要：

The one-dimensional polymer [Ru-2(O2CCF3)(4)(Phz)](infinity) 1 (Phz=phenazine) was synthesized by the reaction of Ru-2(II)(O2CCF3)(4)(THF)(2) with phenazine. An X-ray crystallographic analysis revealed that the compound consists of Ru-2(O2CCF3)(4) units bridged by phenazine ligands. The Ru-Ru bond distance is 2.3109(10) Angstrom and the axial Ru-N distance is 2.425(2) Angstrom. Magnetic measurements performed in the temperature range 1.8-300 K indicate that the S=1 Ru-2(II) units are weakly antiferromagnetically coupled (zJ=-3.0 cm(-1)) with a large zero-field splitting (D=277 cm(-1)).
