## Abstract The oxidation of copper, zinc and nickel by N~2~O~5~ led, respectively, to turquoiseβcoloured single crystals of (NO)Cu(NO~3~)~3~ [monoclinic, __P__2~1~/__m__, __Z__ = 2, __a__ = 465.90(5), __b__ = 1111.7(1), __c__ = 700.7(1) pm, __Ξ²__ = 100.70(2)Β°, __wR__~2~ = 0.0566], lightβyellow sin
The equilibrium constant for the reaction kl (1) NOS-+ HBr 2 Br-+ HNO, has been determined between 331 and 480'K using a variable-temperature flowing afterglow. These data give AH"(1) = -1.03 f 0.21 kcal/mol and AS"(1) = -4.6 f 1.0 cal/mol.'K. When combined with the known thermochemical values for H
Metal Oxidation with N 2 O 5 : The Nitrosylium Nitrates (NO)Cu(NO 3 ) 3 , (NO)2[Zn(NO3)4] and (NO)6[Ni4(NO3)12](NO3)2β’(HNO3). -N2O5 is prepared by reaction of fuming HNO3 with P4O10 and directly condensed on the metal powders. The crystal structures of the resulting title compounds are determined by
