The reactions of (4-methoxyphenyl)boronic acid (1a) and of (2,6-dimethylphenyl)boronic acid (1b) with (PMe₃)₃Rh-(OC₆H₄Me-4) (2) in a 5:1 molar ratio result in the formation of cationic rhodium complexes with new tetraarylpentaborates [Rh(PMe₃)₄]⁺[B₅ O₆Ar₄]^- (3a, Ar = C₆H₄OMe-4; 3b, Ar = C₆H₃Me₂-2,6). The characterization of 3a is as follows: orthorhombic space group P2₁2₁2₁, a = 14.7600(5) Å, b = 17.1675(5) Å, c = 19.8654(5) Å; V= 5033.7(3) Å³; Z = 4. The characterization of 3b is as follows: orthorhombic space group Pnma, a = 23.704(6) Å, b = 17.254(8) Å, c = 13.304(2) Å; V = 5441(2) Å3; Z = 4. An intermediate complex, [Rh(PMe₃)₄]⁺[Ph₃ B₃O₃(OC₆H₄Me-4)]^- (4), was isolated from the reaction of phenylboroxine, (PhBO)₃, with 2. The tetraarylpentaborates smoothly undergo hydrolysis to give [Rh(PMe₃)₄]⁺[B₅ O₆-(OH)4]^- (5).
