Abstract

[Mo2(D-phe)2(L-phe)2]I4·6H2O (1), [Mo2(D-tyr)2(L-tyr)2]I4-6H2O (2), and [Mo2(D-C-phgly)2(L-C-phgly)2](PTS)4-4H2O (3) were obtained by the reaction of Mo24+ with the appropriate DL-amino acid in aqueous solution, followed by the addition of counterions. The structures of 1-3 were determined by X-ray crystallography. 1 is triclinic, space group PĪ, with a = 11.969 (1) Å,b = 13.746 (2) Å, c = 9.457 (1) Å, a = 104.90 (2)°, β = 107.49 (3)°, γ = 66.47 (2)°, V= 1344 (1) Å3, and Z = 1. 2 is triclinic, space group PĪ, with a = 12.666 (1) Å, b = 12.952 (1) Å, c = 8.918 (1) Å, α = 98.50 (3)°, β = 92.31 (2)°, 7 = 63.58 (2)°, V = 1254 (1) Å3, and Z = 1. 3 is triclinic, space group PĪ, with a = 11.361 (1) Å, b = 16.538 (2) Å, c= 10.110 (1) Å, α = 95.44 (2)°, β = 110.84 (2)°, γ = 75.68 (2)°, V= 1720 (1) Å3, and Z = 1. The dimeric molecules in the three structures reside on a crystallographic inversion center, and the four chiral ligands are arranged around the Mo-Mo unit in the cyclic order of DDLL.
