Reactivity of O,N-heterocyclic germylene and stannylene towards μ-dithio-bis(tricarbonyliron)

摘要: Abstract Synthesis and single-crystal X-ray diffraction study (SC-XRD) of the O,N-heterocyclic germylene Ge(PhAp) (1) containing chelate 4,6-di-tert-butyl-N-phenyl-o-amidophenolate ligand (PhApH2, where Ap – o-amidophenolate) are reported. Germylene 1 demonstrates a monomeric structure in contrast to earlier known related stannylene Sn(PhAp) (2) existing as dimer. Diverse weak intermolecular interactions (Ge…Ge, CH…π(chelate) Ge…π(arene)) were detected crystal packing 1. Hirshfeld surface analysis has been performed evaluate such interactions. Reactivity compounds 2 towards dithiodiiron hexacarbonyl examined. Low-valent germanium(II) tin(II) centers readily inserted into S-S bond with formation Fe4(µ4-ES4)(CO)12 (E: Ge(3); Sn(4)) bis-ligand complexes tetravalent metals E(PhAp)2. The resulting germanium(IV) tin(IV) bis-o-amidophenolates isolated six-coordinated pyridine adducts E(PhAp)2(Py)2 Ge(5); Sn(6)). All characterized by SC-XRD.
