Abstract
Two polymeric complexes of glicyne with manganese(II) have been prepared and characterized by means of spectroscopic and x-ray analyses. The first complex of the formula [Mn(Gly)Cl2(H2O)2] crystallizes in the monoclinic space group P21/n with a = 6.519(2), b = 15.981(3), c = 7.893(2) Å, and β = 97.18(3)°. The Mn atoms are in distorted octahedral environments with all ligands in cis positions. The adjacent manganese(II) ions are linked in polymeric chains via carboxylate groups. The second complex [Mn(Gly)2Cl2] crystallizes in the triclinic space group P \(\bar 1\) with a = 4.968(2), b = 6.582(2), c = 7.925(3) Å, α = 106.17(3), β = 92.86(3), and γ = 107.21(3)°. The octahedral-coordinated manganese(II) ion is situated on a crystallographic center of symmetry and is bound to four carboxylate oxygen atoms from different glicyne molecules and two chloride ions.
