Abstract:
The reaction of CoCl2 with succinic acid and isonicotinamide in basic solution produces the title complex [Co(C6H6N2O)2(H2O)4](C4H4O4). The cobalt(II) ion of the complex cation and the succinate anion are each located on an inversion centre. The CoII ion is octa-hedrally coordinated by four O atoms of water mol-ecules and two N atoms of isonicotinamide mol-ecules. The two ions are linked via Owater-H⋯Osuccinate hydrogen bonds, forming chains propagating along [001]. In the crystal, these hydrogen-bonded chains are linked into a three-dimensional framework by further O-H⋯O hydrogen bonds and N-H⋯O hydrogen bonds. The framework is reinforced by C-H⋯O hydrogen bonds. Hirshfeld surface analysis and two-dimensional fingerprint plots have been used to analyse the inter-molecular inter-actions present in the crystal.

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...

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...
02:58Crystal Field Theory - Octahedral Complexes
To explain the observed behavior of transition metal complexes (such as colors), a model involving electrostatic interactions between the electrons from the ligands and the electrons in the unhybridized d orbitals of the central metal atom has been developed. This electrostatic model is crystal field theory (CFT). It helps to understand, interpret, and predict the colors, magnetic behavior, and some structures of coordination compounds of transition metals.
CFT focuses on...
