摘要：

The title host compound forms inclusion compounds with 2,4-, 3,5- and 2,6-lutidine. In each case the host : guest ratio is 1 : 2 and the structures are stabilised by (Host)O-H ... N(Guest) hydrogen bonds. Competition experiments show that the host selects the guests in order of preference of 3,5-lutidine > 2,6-lutidine > 2,4-lutidine. These results are in general agreement with the lattice energy calculations.
