Abstract
Die übergangsmetallsubsituierten Gallane [(CO)5MnGaEt2(NC7H13)] (1), [(PMe3)(CO)3CoGaCl2 · (NMe3)] (2), [(CO)4CoGaEt2(NC7H13)] (3) und [(CO)4CoGaCl3]K (4) wurden durch Reaktion der Carbonylmetallate [(CO)nM] (Na/K) mit den Galliumchloriden ClGaEt2(NC7H13), Cl3Ga(NMe3) bzw. GaCl3 erhalten. Die Einkristallstrukturbestimmungen ergaben für 1: Raumgruppe P21/c (I.T.-Nr.: 14); Z = 4; a = 1425,4(2) pm, b = 1007,4(1) pm, c = 1429,9(3) pm; β = 113,92(1)°; 2: Raumgruppe P21/m (I.T.-Nr.: 11); Z = 2; a = 746,1(1) pm, b = 1131,2(1) pm, c = 1061,5(1) pm; β = 101,87(1)°; 3: Raumgruppe P21/c (I.T.-Nr.: 14); Z = 8; a = 1405,9(2) pm, b = 1786.2(2) pm, c = 1430,9(2) pm; β = 91,47(1)°; 4: Raumgruppe P21/c; Z = 4; a = 1185,7(1) pm, b = 895,4(1) pm, c = 1144,7(3) pm; β = 106,47(2)°. Anhand der Modellverbindungen [{L′(CO)3Co}GaX2L] (L′ = CO, PH3; L = NH3, X = H, Cl) wurden die polaren σ(Co–Ga)-Bindungen und die Substituenteneffekte auf die Bindungslänge auf der Basis quantenchemischer Dichtefunktionalrechnungen (DFT) charakterisiert.
Transition Metal substituted Gallanes: Synthesis and X-Ray Structures of [(CO)4CoGaEt2(NC7H13)], [(PMe3)(CO)3CoGaCl2(NMe3)], [(CO)4CoGaCl3]K, and [(CO)5MnGaEt2(NC7H13)]
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 cobaltcarbonylmetallates with the chlorogallium species ClGaEt2(NC7H13), Cl3Ga(NMe3), and GaCl3. The structures were established by single crystal X-ray analysis 1: space group P21/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 P21/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 P21/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 P21/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.
