Abstract: | A new alternating double aquo-bridged and single cyano-bridged polymeric complex {Ba2(phen)4(H2O)6Fe(CN)6]·Cl·2(phen)·3H2O}n (1) (phen = 1,10-phenanthroline) has been synthesized and structurally characterized. In the crystal structure the two centrosymmetric Ba2(phen)4(H2O)6] units are bridged through two trans CN groups of Fe(CN)6]3− ion, which results in the formation of a zig-zag polymeric chain. In each Ba2(phen)4(H2O)6] unit, the two Ba centers are joined by double aquo bridges. Both the Ba atoms are 9-coordinated with distorted mono-capped square antiprismatic geometry. An elaborate hydrogen bonding system holds the parallel polymeric chains together. |
