Aggregates of the [GaCl4]− anion and the [Ga(H2O)3(NCS)3] complex with 18C6
摘要:
The complex formation in the system GaCl3-ROH-MNCS-18K6 is considered (ROH = MeOH, EtOH; M = Na, K; 18C6 is 1,4,7,10,13,16-hexaoxocyclooctadecane). Two modifications of [Na(18C6)][GaCl4], namely, aggregates [Na(18C6)][GaCl4](MeOH)(0.9)(EtOH)(1.1) and [Ga(H2O)(3)(NCS)(3)] center dot 18C6, are synthesized and identified. The Ga-71 NMR (solutions) and X-ray diffraction studies showed that the compositions and structures of the title compounds are determined by the ratio of the competing acido ligands (Cl- and NCS-) in the reaction solution.
