title: Di-μ-cyanido-1:2κC:N,2:3κN:C-hexa-cyanido-1κC,3κC-tetra-kis(1,10-phenanthroline)-1κN,N';2κN,N';3κN,N'-1,3-dicobalt(III)-2-iron(II) tetra-hydrate.
abstract: The hydro-thermal reaction of CoCl(2)·6H(2)O, 1,10-phenanthroline (phen) and K(3)[Fe(CN)(6)] in deionized water yielded the title cyanide-bridged trinuclear cluster, [Co(2)Fe(CN)(8)(C(12)H(8)N(2))(4)]·4H(2)O or [{Co(III)(phen)(CN)(4)}(2){Fe(II)(phen)(2)}]·4H(2)O, which contains two Co(III) centers and one Fe(II) center linked by cyanide bridges. The combination of coordinative bonds, O-H⋯N and O-H⋯O hydrogen bonds and π-π stacking inter-actions [centroid-centroid distance = 3.630 (2) Å] results in the stabilization of a supra-molecular structure. All uncoordinated water molecules are disordered. Thermogravimetric analysis reveals that the title complex loses the four crystal water mol-ecules at about 333 K, then the anhydrous phase loses no further mass up to about 573 K, above which decomposition occurs.
