The reactions of (4-methoxyphenyl)boronic acid (1a) and of (2,6-dimethylphenyl)boronic acid (1 b) with (PMe3)(3)Rh-(OC6H4Me-4) (2) in a 5:1 molar ratio result in the formation of cationic rhodium complexes with new tetraarylpentaborates [Rh(PMe3)(4)](+)[B5O6Ar4](3a, Ar = C6H4OMe-4; 3b, Ar = C6H3Me2-2,6). The characterization of 3a is as follows: orthorhombic space group P2(1)2(1)2(1), a = 14.7600(5) Angstrom, b =17.1675(5) Angstrom, c = 19.8654(5) Angstrom; V = 5033.7(3) Angstrom(3); Z = 4. The characterization of 3b is as follows: orthorhombic space group Pnma, a = 23.704(6) Angstrom, b = 17.254(8) Angstrom, c = 13.304(2) Angstrom; V = 5441(2) Angstrom(3); Z = 4. An intermediate complex, [Rh(PMe3)(4)](+)[Ph3B3O3(OC6H4Me-4)](-) (4), was isolated from the reaction of phenylboroxine, (PhBO)(3), with 2. The tetraarylpentaborates smoothly undergo hydrolysis to give [Rh(PMe3)(4)](+)[B5O6(OH)(4)](-) (5).
