Abstract
Two types of polymeric copper(II) complexes, [Cu(trifac)2(4-tfmpda)]2 (1), and [Cu2(hfa)4(4-tfmpda)] (2) were obtained from the reaction of bis(fluorinated-acetylacetonato)copper(II) complexes with 4-(trifluoromethyl)-1,2-phenylenediamine[4-tfmpda] in methylene chloride. 1 crystallizes in the monoclinic space group P2(1)/c, with a=7.840(2) Å, b=11.659(3) Å, c=22.843(6) Å, V=2075.1(9)Å3, and Z=2 with R=0.0474. 2 crystallizes in the triclinic space group P1̄, with a=11.644(3) Å, b=12.599(4) Å, c=15.171(4) Å, V=1924.5(10)Å3, and Z=2 with R=0.0686. 1 exists as a 1-D infinite polymeric chain where 4-tfmpda is linked by weak coordination bonds around two copper(II) centers, while 2 is a 1-D polymer formed by hydrogen bonds and very weak Cu⋯Cu interactions.
