title: Transformations of the chameleon ligand 1,10-phenanthroline-5,6-dione/diol: cis-dichlorido(1,10-phenanthroline-5,6-dione-kappa2N,N')-trans-dipyridinecobalt(II) pyridine disolvate prepared from the diol.
abstract: The title compound, [CoCl2(C(5)H(5)N)2(C(12)H(6)N(2)O(2))].2C(5)H(5)N, is a neutral Co(II) complex with two chloride anions coordinated in a cis fashion, two pyridine ligands in trans positions and a chelating 1,10-phenanthroline-5,6-dione ligand that completes the octahedral coordination geometry. Two pyridine solvent molecules reside in channels (about 7 x 4 A wide; the closest atom-atom distance within the channel is 10 A). The three-dimensional structure supporting these channels is held together by C-H...Cl [3.466 (8)-3.670 (9) A] and C-H...O [3.014 (9)-3.285 (8) A] hydrogen bonds, and can be viewed as a CsCl or bcu (body-centred cubic) net.
