摘要

The transition metal substituted gallanes [(CO)5MnGaEt2(NC7H13)] (1), [(PMe3)(CO)3CoGaCl2 · (NMe3)] (2), [(CO)4CoGaEt2(NC7H13)] (3), and [(CO)4CoGaCl3]K (4) were obtained by the reaction of the potassium/sodium salts of the manganese-and cobalt-carbonylmetallates with the chlorogallium species ClGaEt2(NC7H13), Cl3Ga(NMe3), and GaCl3. The structures were established by single crystal X-ray analysis 1: space group P2l1/c (I.T.-No.: 14); Z = 4; a = 1425.4(2) pm, b= 1007.4(1 )pm, c = 1429.9(3) pm; β = 113.92(1)°; 2: space group P2l/m (I.T.-No.: 11); Z = 2; a = 746.1(1) pm, b = 1131.2(1) pm, c = 1061.5(1) pm; β = 101.87(1)°; 3: space group P2l/c (I.T.-No.: 14); Z = 8; a = 1405.9(2) pm, b = 1786.2(2) pm, c = 1430.9(2) pm; β = 91.47(1)°; 4: space group P2l/c; Z = 4; a = 1185.7(1) pm, b = 895.4(1) pm, c = 1144.7(3) pm; β = 106.47(2)°. The model compounds [{L′(CO)3Co}GaX2L] (L′= CO, PH3; L = NH3, X = H, Cl) with polar σ(Co-Ga) bonds and the effect of the substituent on the bond length are characterized with DFT-calculations.
