摘要：

The [M(28C6)](4)[Sc(NCS)(6)]Cl center dot nH(2)O complexes were established to form in the solutions ScClx-Sov-NiNCS-18C6, where Solv is ethanol, THF, acetonitrile, or isopropyl alcohol; M = Na, K: 18C6 is 1,4,7,10,13,16-hexaoxocyclooctadecane. X-ray diffraction analysis of [K(18K6)](4)[Sc(NCS)(6)]Cl center dot 3.33H(2)O showed that the thiocyanate ion was coordinated by Sc through the N atom. The structure consists of octahedral Sc(NC S)(6)(3-) that are united via nonvalent K-S interaction with macrocyclic dimers [M(18C6)](2) into chains. Each 18C6 molecule coordinates one K atom.
