A polymeric manganese(II) complex, [MnL2Cl2](n) (L = 2-amino-4-methylpyrimidine) has been synthesized by the reaction between MnCl2 center dot 4H(2)O and L in the 1:1 and 1:2 metal-to-ligand molar ratios. The Mn2+ ions adopt distorted octahedral environment formed by four Cl- ligands and two N-1 atoms of the pyrimidine rings of two L molecules. The chlorido-ligands adopt a mu(2)-bridging coordination mode linking manganese atoms into the polymeric chain. The free ligand L shows excitation-wavelength-dependent emission originating from the pi-pi* and n-pi* excited states with nanosecond lifetimes in the blue region of the spectrum. The complex [MnL2Cl2](n) demonstrates photoluminescence with the maximum in the near-infrared region (lambda(max) = 740 nm, phi = 1.7%) with microsecond lifetimes (tau = 124 mu s).
