Spodium bonds and metal–halogen···halogen–metal interactions in propagation of monomeric units to dimeric or polymeric architectures

Comparison of Intermolecular Halogen...Halogen Distances in Organic and Organometallic Crystals

“…. .Hal-M have rarely been noted by researchers [37]. Therefore, one of the goals of this work was to statistically analyze the M1-Hal1.…”

Noncovalent interactions in proteins and nucleic acids: beyond hydrogen bonding and π-stacking

“…A few recent studies on the X-ray crystal structure analysis of metal complexes of Zn, Cd, and Hg and theoretical understanding of small model molecules evidence the existence and importance of Sp-bonds in crystal engineering. 164–172 This paves the way for expanding their chemistry further in biomolecules. The abundance of zinc in biological systems indicates the possibility of the presence of Sp-bonds in biomolecules.…”

The importance of spodium bonds, H-bonds and π-stacking interactions in the solid state structures of four zinc complexes with tetradentate secondary diamine ligands

“…Interestingly, complexes 1 and 2 incorporate co-crystallized solvent molecules (DMSO) that interact with the complexes by means of the electron rich oxygen-atom establishing concurrent H-bonds and spodium bonds (SpBs). The latter interactions have attracted the attention of the scientific community 41,[46][47][48][49][50][51][52][53][54] along with other non-covalent interactions involving metals, like coinage bonds 55 for group 11, osme bonds 56 for group 8, matere bonds 57 for group 7 and wolfium bonds 58 for group 6. These types of s-hole non-covalent interactions involving metal centers have been studied in detail [46][47][48][49][50][51][52][53][54][55][56][57][58] and it has been demonstrated that their physical nature is different compared to conventional coordination bonds (strong covalent character).…”

In the present case, we have synthesized four zinc complexes to study spodium bonds, if any, in their solid state structures.…”
