Abstract:
The asymmetric unit of the title compound, [MnBr(2)(C(8)H(6)N(4))(2)]·CH(3)NO(2), contains one half of a neutral Mn(II) complex and one half of a nitro-methane solvent mol-ecule, the complete mol-ecules being generated by the application of twofold symmetry. In the complex, the Mn(II) ion has a distorted cis-Br(2)N(4) octa-hedral coordination geometry defined by four N atoms of the two chelating 2,2'-bipyrimidine ligands and two Br(-) ions. There are intra- and inter-molecular C-H⋯Br and C-H⋯N contacts.

Structural 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 be...

Stereoisomerism
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...
Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...
Spin–Spin Coupling Constant: Overview
Qualitatively, any spin plus-half nucleus polarizes the spins of its electrons to the minus-half state. Consequently, the paired electron in the hydrogen–carbon bond must have a...
