Can the solid state structures of the dihalogen adducts R3EX2 (E = P, As; R = alkyl, aryl; X = Br, I) with the molecular spoke geometry be considered good mimics of the gold(i) systems [(R3E)AuX] (E = As, P; R = alkyl, aryl; X = Cl, Br, I)?

 Can the solid state structures of the dihalogen adducts R3EX2 (E = P, As;
 R = alkyl, aryl; X = Br, I) with the molecular spoke geometry be
 considered good mimics of the gold(i) systems [(R3E)AuX] (E = As, P; R =
 alkyl, aryl; X = Cl, Br, I)?
