Abstract:
This work describes the photoreactivity and photosalient (PS) behavior of five new isotypical Cd(II) coordination complexes [Cd(bz)2(4-nvp)2] (1), [Cd(4-clbz)2(4-nvp)2] (2) and (3), and [Cd(4-brbz)2(4-nvp)2] (4) and (5) [Hbz = benzoic acid, H4-clbz = 4-chlorobenzoic acid, and H4-brbz = 4-bromobenzoic acid]. Complexes 2 and 3 are 4-clbz based polymorphs, while 4 and 5 are 4-brbz based polymorphs. Interestingly, complexes 1, 2 and 4 form head-to-head (HH) dimers, while 3 and 5 form head-to-tail (HT) dimers through photodimerization.

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...
Thermal Electrocyclic Reactions: Stereochemistry
Selection Rules: Thermal Activation
Conjugated systems containing an even number of π-electron pairs undergo a conrotatory ring closure. For example, thermal electrocyclization of (2E,4E)-2,4-hexadiene, a conjugated diene containing two π-electron pairs, gives trans-3,4-dimethylcyclobutene.
