Abstract
Two new transition metal complexes [Co(tmbpm)Cl2(H2O)]×2H2O (1) and [Zn(tmbpm)Cl2]×2H2O (2) (where tmbpm = 4,4',6,6'-tetramethyl-2,2'-bipyrimidine) are synthesized and characterized by IR and single crystal X-ray diffraction. The tmbpm adopts chelating coordination mode in the two mononuclear complexes. Both 1 and 2 form 2D supramolecular structures containing an infinite 1D water chain through hydrogen bonds.
