The chalcogen bond (ChB) is defined as a noncovalent interaction between the electron
density deficient region (so-called as σ or π hole) of a covalently bonded chalcogen atom …

This review highlights recent studies discovering unconventional halogen bonding (HaB)
that involves positively charged metal centers. These centers provide their filled d‐orbitals …

Over the past several decades, halogen bonding has become a standard 'tool'in
supramolecular chemistry and particularly in crystal engineering. Traditionally, the study of …

Elements from groups 14–18 and periods 3–6 commonly behave as Lewis acids, which are
involved in directional noncovalent interactions (NCI) with electron-rich species (lone pair …

Three diaryliodonium tetrachloroaurates (III),[Ar1IAr2][AuCl4](Ar1/Ar2= Ph/Ph (1), Ph/Mes
(2), o-(C6H4) 2 (3)), were obtained as solids (62–80%) by the metathetical reaction of …

Platinum (II) complexes exhibiting an expressed dz 2-nucleophilicity of the positively
charged metal centers, namely,[Pt (ppy)(acac)](1; acacH is acetylacetone; ppyH is 2-Ph …

The complexes [RhX (COD)] 2 (X= Cl, Br; COD= 1, 5-cyclooctadiene) form cocrystals with σ-
hole iodine donors. X-ray diffraction studies and extensive theoretical considerations …

Hypervalent iodine (III)-derivatives display higher catalytic activity than other aliphatic and
aromatic iodine (I)–or bromine (I)-containing substrates for a Knorr-type reaction of N-acetyl …

Synthesis and X-ray characterization of the four diaryliodonium tetrachloroplatinates
(II)[Ar1Ar2I] 2 [PtCl4](Ar1/Ar2= Ph/Ph (1), 4-Cl-C6H4/2, 4, 6-(MeO) 3C6H2 (2), 4-Me-C6H4/2 …

Iodopentafluorobenzene (IPFB or PhFI) was co-crystallized with tetra (n-butyl) ammonium
tetraiodo-μ, μ′-diiododiplatinate (II),[n-Bu4N] 2 [Pt2 (μ-I2) I4](1), to give the adduct 1· 2IPFB …
