| Abstract: | Two dimethyl-substituted cucurbit5]uril (DMeQ5]) complexes with heterometallic potassium/gadolinium metal ions and with potassium ions only were structurally characterized by single-crystal X-ray diffractions. They are {K2(H2O)3DMeQ5]}I2·5H2O (1) and {Gd(H2O)3]K(H2O)](NO3)@DMeQ5]]}(NO3)3·5H2O (2). Compared to the complex of DMeQ5] with gadolinium metal ions only, both opening portals of DMeQ5] are fully capped by potassium cations or potassium and gadolinium cation ions in these two DMeQ5]-based complexes.
