Abstract

A series of complexes of Ar-SO2-N-amino acids (Ar-SO2-= 4-toluensulfonyl- (hereafter abbreviated as tosyl) (ts), benzenesulfonyl (bs); amino acid=glycine (gly), DL-alpha- and beta-alanine (alpha- and beta-ala), asparagine (asn) and glutamine (gln)) with Mn(II) was synthesized and characterized by means of spectroscopic and thermal analyses. For two of them [Mn(ts-alpha-ala)2(H2O)].2.78H2O.0.92CH3OH (1) and [Mn(tsgln)2] (II) the crystal and molecular structure was also determined. I crystallizes in the orthorhombic Pbcn space group, with cell dimensions: a = 31.212(3), b = 11.248(2), c = 9.051(2) angstrom, Z = 4. II crystallizes in the monoclinic C2 space group, with cell dimensions: a = 17.490(3), b = 5.259(2), c = 17.432(2) angstrom, beta = 120.70(4)-degrees, Z = 2. In both compounds the Mn(II) atom is octahedrally coordinated by six oxygen atoms. In I the amino acid monoanion bridges two Mn atoms through the carboxyl group giving rise to a 1D polymer, the coordination to Mn is completed by two water molecules in a special position. In II each amino acid monoanion bridges two Mn atoms through the carboxyl group and binds a third Mn atom through the carbonyl oxygen of the terminal amide group, giving rise to a 2D polymer.
