The structure of triphenyl(1-phenyl-5-mercapto-1H-1,2,3,4-tetrazolato)lead(IV): towards the first example of a π-coordinated metallotetrazole?
摘要:
The structure of the organolead thiotetrazolate 5-(Ph3PbS)CN4Ph-1 has been determined and incorporates intermolecular N-Pb interactions that are suggestive of the onset of pi-coordination. (C) 1999 Elsevier Science S.A. All rights reserved.
The title compound, [Ag(C7H5N4S)(C18H15P)(2)]. CH3OH, contains trigonal-planar silver coordinated to the thiotetrazole ligand via sulfur. The presence of methanol, which hydrogen bonds to the tetrazole ring, weakens the donor capacity of the ring N atoms, preventing their interaction with silver.
