Glycine-templated manganese sulfate with new topology and canted antiferromagnetism.

A new glycine-templated manganese(II) sulfate, (C(2)NO(2)H(5))MnSO(4) (1), has been solvothermally synthesized and characterized crystallographically and magnetically. Crystal data for 1: monoclinic, space group P2(1)/m, a = 4.8884(10) A, b = 7.8676(14) A, c = 8.0252(15) A, beta = 106.524(2) degrees , V = 295.90(10) A(3), Z = 2. The glycine bridges Mn(II) ions in mu(2) mode and sulfate in eta(3),mu(4) mode. Along the b direction, the neighboring Mn(II) ions were bridged to each other by two sulfate ions and one glycine ligand to form a triple-stranded braid. The adjacent braids were connected via the sulfate ions to give a two-dimensional framework with a novel binodal 4,6-connected (3(2);4(2);5(2))(3(4);4(4);5(4);6(3)) topology. The compound exhibits a spin-canted antiferromagnetic behavior with a weak ferromagnetic transition below 9 K, and the estimated canting angle is 0.13 degrees.
