(NR4)W2Cl9 and (NR4)(2)W2Cl10, prepared by addition of NR4Cl (R = alky
l) to (WCl4)(x) powder in CH2Cl2, have confacial [W=W, 2.689(1) Angstr
om] and edge-sharing bioctahedral [W=W, 2.792(1) Angstrom] structures,
respectively, as NBnEt3+ salts, and convert with added NR4Cl to (NR4)
(2)W2Cl9 and (NR4)WCl6 and eventually (NR4)(2)WCl6; (NR4)W2Cl9 can be
converted to (NR4)(2)W2Cl10 by NR4Cl at -30 degrees C.
