Synthesis, Crystal Structure and Luminescent Property of Mg(II) Complex with N-Benzenesulphonyl-L-Leucine and 1,10-Phenanthroline

A new complex [Mg(L)(2)(phen)(H(2)O)(2)](phen)(H(2)O)(2) [L= N-benzenesulphonyl-L-leucine] was synthesized by the reaction of magnesium chloride hexahydrate with N-benzenesulphonyl-L-leucine and 1,10-phenanthroline in the CH(3)CH(2)OH/H(2)O (v:v = 5:1). It was characterized by elemental analysis, IR and X-ray single crystal diffraction analysis. The crystal of the title complex [Mg(L)(2)(phen)(H(2)O)(2)](phen)(H(2)O)(2) belongs to triclinic, space group P-1 with a = 0.72772(15) nm, b = 1.4279(3) nm, c = 1.4418(3) nm, α = 63.53(3)°, β = 79.75(3)°, γ = 81.83(3)°, V = 1.3163(5) nm(3), Z =1, D(c)= 1.258 μg·m(−3), μ = 0.177 mm(−1), F(000) = 526, and final R(1) = 0.0506, ωR(2) = 0.1328. The complex comprises a six-coordinated magnesium(II) center, with a N(2)O(4) distorted octahedron coordination environment. The molecules are connected by hydrogen bonds and π-π stacking to form one dimensional chain structure. The luminescent property of the Mg(II) complex has been investigated in solid.
