Abstract

Title full: Metal complexes of 2,4-diamino-5-(3′,4′,5′-trimethoxybenzyl)pyrimidine (trimethoprim) and 2,4-diamino-5-(p-chlorophenyl)-6-ethylpyrimidine (pyrimethamine). Part III. Syntheses and x-ray structures of [Rh2(O2CCH3)4(trimethoprim) 2]·2C6H6·CH3OH and [Rh2(O2CCH3)4(pyrimethamine) 2]. The syntheses and structures of [Rh2(O2CCH3)4- Trim2]·2C6H6·C H3OH (1) and [Rh2(O2CCH3)4- Pyr2] (2) are reported. Compound 1 crystallizes in the monoclinic space group C2/c with a = 24.135- (5), b = 15.196(14), c = 16.536(3) Å, β = 116.85(2)° and Z = 4. The Trim ligands coordinate the two axial positions of the dirhodium tetraacetato moiety through the pyrimidinic nitrogen N(1) with a Rh N(1) bond length of 2.289(2) Å. Compound 2 is monoclinic, space group C2/m with a = 24.200(6), b = 10.295(3), c = 7.474(2) Å, β = 90.61(3)° and Z = 2.
