| Abstract: | Two new cyano-bridged trinuclear heterometallic complexes Sr2(Phen)4(CF3CO2)(H2O)3Fe(CN)6]·2H2O (1) Ca2(Phen)4(CF3CO2)(H2O)Co(CN)6]·2H2O (2) (where Phen=1,10-phenanthroline) have been synthesized and their crystal structures have been determined. The structure of complex (1) features a central Fe(CN)6]3− unit that links a monocation, Sr(Phen)2(OH2)(OOCCF3)]+ and a dication, Sr(Phen)2(OH2)2]2+ via two trans cyanide bridges. The complex (2) features a central Co(CN)6]3− unit that links two monocations of Ca(Phen)2(OH2)(OOCCF3)]+ (the positions of the trifluoro acetate and water molecules are disordered over two positions) via two trans cyanide bridges. Each metal atom is seven coordinated and achieves pentagonal bipyramidal geometry. Two cocrystallized water molecules are present in both the complexes. The presence of an extensive network of hydrogen bonding imparts the overall stability to both the systems. |
