摘要：
A new cyano-bridged trinuclear complex [Sr-2(phen)(4)(H2O)(3)(NO3)Fe(CN)(6)].1.25 H2O (1) (where phen = 1,10-phenanthroline) has been synthesised and its crystal structure determined. The structure features a central [Fe(CN)(6)](3-) unit that links a [Sr(phen)(2)(OH2)(2)](2+) dication and a [Sr(phen)(2)(OH2)(NO3)](+) monocation via two trans cyanide bridges. In the dicationic part, the Sr centre achieves a pentagonal bipyramidal geometry whereas in the monocationic part, the Sr centre shows a square antiprismatic geometry. The presence of an extensive network of hydrogen bonds imparts the overall stability to the system.
