Tetraphenylphosphonium tetrakis(1-methyl-1,2,3,4-tetrazole-5-thiolato-S)- aurate(III) hemihydrate

The tetraphenylphosphonium salt of tetra(1-methyl-1,2,3,4-tetrazole-5-thiolato)aurate(III) crystallizes as H2O solvate in the monoclinic space group C2/c with the gold atom situated on an inversion centre. The tetrazole rings are arranged almost orthogonally to the square coordination sphere. Au-S-C angles of 106.16(11) and 107.14(12)° have been found.
