摘要：
The compounds [Sc(H2O)(4)(NCS)(2)][Sc(H2O)(2)(NCS)(4)] center dot 2(18C6) (I) and [Sc(H2O)(4)(NCS)(2)][Sc(H2O)(2)(NCS)(4)] center dot 3(18C6) center dot H2O (II) were synthesized and studied by X-ray diffraction analysis. It was found that the cations in the structures of compounds I and II form sandwiches [Sc(H2O)(4)(NCS)(2)] center dot 2(18C6). In the case of I, the sandwiches are united by the [Sc(H2O)(2)(NCS)(4)](-) anions into chains, while in compound II, the sandwiches and infinite chains of [Sc(H2O)(2)(NCS)(4)] center dot 18C6 center dot H2O are bonded by van der Waals contacts only.
