Abstract:
In the context of the importance of manganese β-diketonates as precursors for the preparation of manganese oxide thin films and nanostructured materials, we report synthetic protocols and pitfalls encountered in the preparation of a family of Mn(ii) complexes of two fluorinated β-diketonates, 1,1,1-trifluoroacetylacetonato- (tfac) and 1,1,1,5,5,5-hexafluoroacetylacetonato- (hfac). The synthetic conditions and crystal structures of six new complexes are reported, including a coordination polymer {K[Mn(tfac)3]}∞, an unusual trinuclear complex Mn3(tfac)6(OH2)2, and a series of mononuclear complexes with coordinated solvents tetrahydrofuran, 1,2-dimethoxyethane, water, and acetonitrile. The crystal structures of two known Mn(ii) complexes are also reported for completeness.

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...
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...
02:17Regioselectivity of Electrophilic Additions to Alkenes: Markovnikov's Rule
The hydrohalogenation of an unsymmetrical alkene can yield two haloalkane products, depending on which vinylic carbon takes up the halogen. However, one product usually predominates, where hydrogen adds to the vinylic carbon bearing the...
