Methanesulfonate salts have garnered interest as candidates for optical crystals; however, there are relatively little empirical data to thoroughly understand their structure-property relationships. Furthermore, there is only one trivalent main group methanesulfonate reported in the solid state, Al(H2O)6(SO3CH3)3. We report the synthesis and characterization of four new trivalent methanesulfonates, such as (I) Y(SO3CH3)3, (II) Bi(SO3CH3)3, (III) In2(SO3CH3)6(H2O)6, and (IV) Sb2O2(OH)(SO3CH3). Compounds I, II, and IV crystallize in the monoclinic space group P21/c (no. 13), whereas III crystallizes in the triclinic space group P1̅ (no. 2). Each compound exhibits wide optical transparency from 300 to 1200 nm and is thermally stable up to 300-400 °C. Their synthesis, structure, optical properties, and thermal stabilities are discussed.

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...
02:52Stereoisomerism
Isomers are different chemical species that have the same chemical formula.
Transition metal complexes often exist as geometric isomers, in which the same atoms are connected through the same types of bonds but with differences in their orientation in space. Coordination complexes with two different ligands in the cis and trans positions from a ligand of interest form isomers. For example, the octahedral [Co(NH3)4Cl2]+ ion has two isomers (Figure 1) In the cis...

02:34Structural Isomerism
Isomers are different chemical species that have the same chemical formula. Structural isomerism of coordination compounds can be divided into two subcategories, the linkage isomers and coordination-sphere isomers.
Linkage isomers occur when the coordination compound contains a ligand that can bind to the transition metal center through two different atoms. For example, the CN− ligand can bind through the carbon atom or through the nitrogen atom. Similarly, SCN− can...
