Abstract: Two new cyano-bridged trinuclear heterometallic complexes [Ca2(phen)4(ClO4)(H2O)3-
Fe(CN)6]·H2O (1) and [Ca2
(phen)4(CH3COO)(H2O)3Fe(CN)6]·2H2O (2) (where phen = 1,10-
phenanthroline) have been synthesized and characterized by single-crystal X-ray diffraction techniques,
IR spectroscopyand thermogravimetric analysis. The structure of complex 1 features a central
[Fe(CN)6]3− unit that links a monocation [Ca(phen)2(H2O)(ClO4)]+ and a dication [Ca(phen)2-
(H2O)2]2+ via two trans cyanide bridges. Similarly, complex 2 also features a central [Fe(CN)6]3−
unit that links a monocation [Ca(phen)2(H2O)(CH3COO)]+ and a dication [Ca(phen)2(H2O)2]2+ via
two trans cyanide bridges. In 1 and 2, both Ca centers are seven-coordinated and achieve a pentagonal-
bipyramidal geometry whereas the Fe center in both the complexes possesses a distorted octahedral
geometry. Intra- and intermolecular hydrogen bonding networks are present in 1 and 2 that
impart the overall molecular stabilityto both the systems.
