Abstract:
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.

Colors and Magnetism
When atoms or molecules absorb light at the proper frequency, their electrons are excited to higher-energy orbitals. For many main group atoms and molecules, the absorbed photons are in the ultraviolet range of the electromagnetic spectrum, which cannot be detected by the human eye. For coordination compounds, the energy difference between the d orbitals often allows photons in the visible range to be absorbed and emitted, which is seen as colors by the human eye.
Ionic Crystal Structures
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
