Adamantane‐type organotin chalcogenide clusters of the general composition [(RT)4S6] (R=aromatic substituent, T=Si, Ge, Sn) have extreme non‐linear optical properties that lead to highly directional white‐light generation (WLG) upon irradiation with an IR laser diode. However, the mechanism is not yet understood. Now, a series of compounds [(RSn)4E6] (R=phenyl, cyclopentadienyl, cyclohexyl, benzyl, CH2CH2(C6H4)CO2Et; E=S, Se), were prepared, characterized, and investigated for their nonlinear optical properties. With the exception of crystalline [(BnSn)4S6], all these compounds exhibit WLG with similar emission spectra; slight blue‐shifts are observed by introduction of cyclopentadienyl substituents, while the introduction of Se in the inorganic core can provoke a red‐shift. These investigations disprove the initial assumption of an aromatic substituent being a necessary precondition; the precondition seems to be the presence of (cyclic) substituents providing enough electron density.

“…This type of rearrangement reaction has already been explained in the literature. [55][56][57][58][59][60][61] Furthermore, the formation of ladder-like oxobridged compounds can be rationalized by phenyl group cleavage, as observed during the reaction between bis(triphenyltin) oxide and carboxylic acids reported by Chandrasekhar et al [62] In this case, it is expected that rearrangement of PhSnCl 3 (start-ing material) gives Ph 2 SnCl 2 and SnCl 4 . The former rearrangement product may be hydrolysed to form Ph 2 SnO and the latter treated with H 3 L to form a chloro derivative, which further hydrolyses to form a μ-oxo-bridged dimer.…”

Three novel atrane-like pentacoordinate silicon and hexa-and mixed penta-and hexacoordinate tin compounds containing [4.4.3.0]tridecane cages have been synthesized. In the present work, the bis-phenol amine tetradentate ligand, N,N-bis(2-hydroxy-3,5-dimethylbenzyl)-2-aminoethanol (H 3 L), was treated with phenyltrichlorosilane, butyltrichlorostannane and phenyltrichlorostannane to give the mononuclear pseudosilatrane 1, dinuclear pseudo-stannatrane 2 and tetranuclear pseudo-stannatrane 3, respectively. These compounds were characterized by spectroscopic techniques ( 1 H,
