abstract
The coordination complex namely diaqua 1,10-phenanthroline cobalt (II) 2,5-pyridine dicarboxylate monohydrate that is formulated as [Co(H2O)(2)(PHEN)(PDC)] H2O, (PHEN is the abbreviation of 1,10-phenanthroline and PDC is the abbreviation of 2,5-pyridinedicarboxylate), has been hydrothermally synthesized and characterized via single crystal X-ray diffraction techniques. This compound is monoclinic, space group P21/c, with Z = 4 in a unit cell with dimensions a = 11.7840(5) , b = 7.5298(3) , c = 21.5238(9) , beta = 93.124(3)A degrees. The structure contains one crystallographic unique Co atom, two coordinate water molecules, one PHEN species, one PDC fragment and one lattice water molecule. Extensive water O-H center dot center dot center dot O hydrogen bonding interaction among the adjacent discrete molecules leads to a two dimensional framework. This structure represents the first of cobalt compound in the system of PDC and PHEN that has been reported.
