Abstract
Crystals of [Me3Ga2(N2C4H5)3CuO]2 are monoclinic, a = 10.766(1), b = 14.419(2), c = 15.174(1) Å, β = 115.923(6)°, Z = 2, space group P21/c. The structure was solved by Patterson and Fourier syntheses and was refined by full-matrix least-squares procedures to a final R of 0.047 and Rw of 0.060 for 3042 reflections with I ≥ 3σ(I). Details of the preparation and physical properties of the compound are given. The centrosymmetric binuclear complex features copper atoms having distorted square-pyramidal geometry, bonded to four nitrogen atoms and one oxygen atom. Bond distances in the molecule are: Cu—O, 1.923(3), Cu—N, 1.964(4)–2.874(4), Ga—O, 1.825(4) and 1.881(3), Ga—N, 1.952(4)–1.978(5), Ga—C, 1.950(7)–1.979(8), N—N, 1.358(6)–1.385(6), N—C, 1.326(7)–1.352(6), C—C(pyrazolyl), 1.342(9)–1.386(8), C—CH3, 1.487(9)–1.500(10), and C—H, 0.81(10)–1.06(12) Å.Keywords
