(HgBr2)3(As4S4)2: An Adduct of HgBr2 Molecules and Undistorted As4S4 Cages

(HgBr2)3(As4S4)2 is obtained by high temperature reaction of stoichiometric amounts of HgBr2 and As4S4. It crystallizes in the monoclinic space group P21/c with the lattice constants a = 9.593(5) Å, b = 11.395(5) Å, c = 13.402(5) Å, β = 107.27(3)°, V = 1399(1) Å3, and Z = 2. The crystal structure co...

Summary:(HgBr2)3(As4S4)2 is obtained by high temperature reaction of stoichiometric amounts of HgBr2 and As4S4. It crystallizes in the monoclinic space group P21/c with the lattice constants a = 9.593(5) Å, b = 11.395(5) Å, c = 13.402(5) Å, β = 107.27(3)°, V = 1399(1) Å3, and Z = 2. The crystal structure consists of molecular units built from two undistorted As4S4 cages which are coordinated weakly by three almost linear HgBr2 units. Raman spectra clearly indicate minor bonding interactions between HgBr2 and As4S4.
