Mixed potassium -ferrous ferrocyanide and its R u11 and O s11 analogs have been synthesized tribochem ically by grinding F e (S 0 4)-7 H 20 with the equivalent am ount of K4[Fe(CN )6]3 H 20 and the R u11 and O s11 compounds. Their X R D pow der patterns and M össbauer and IR spectra w ere recorded and in terpreted . The role of hydration w ater on the feasibility of the tribochem ical synthesis...

A generalized triangle group is a group that can be presented in the form G = 〈 x, y | x = y = w(x, y) = 1 〉 where p, q, r ≥ 2 and w(x, y) is an element of the free product 〈 x, y | x = y = 1 〉 involving both x and y. Rosenberger has conjectured that every generalized triangle group G satisfies the Tits alternative. It is known that the conjecture holds except possibly when the triple (p, q, r)...
