The making of mechanically interlocked molecular compounds [1] has evolved from a statistical beginning [2] to the use of molecular-recognition-driven, self-assembly protocols [3] that rely upon the operation of covalent, [4] metal, [5] or noncovalent [6] templates, [7] prior to the formation of the mechanical bond(s) by either kinetically or thermodynamically controlled processes, involving either dative [8] or covalent [9] bond formation. Previously, we have speculated [10] about the existence of another class of interlocked molecule beyond the archetypal catenanes [11] and rotaxanes, [12] which are not all that dissimilar from carceplexes [13] and yet are distinguishable from them. [14] In searching for some simple term for this class of mechanically interlocked molecule (Figure 1), which consists of two separate components-a body with two or more limbs that are rigid and protrude outwards, the torso of which carries a close-fitting, all-in-one suit, such that it encompasses the torso of the body-we have come up with the term suitane, in which a number is inserted between "suit" and "ane" to indicate the number of protruding limbs. Thus, the simplest member of the series would be suit Let us consider the specific example (Scheme 1) of a linear body template [15] LBT-H 2 2+ carrying two -CH 2 -NH 2 + CH 2 -recognition sites separated from each other by a bulky midriff [16] such that the double linking up of two matching [24]crown-8 rings in the shape of (CHO) 2 -DP24C8 units [17] can be achieved reversibly by forming four imine bonds with a diaminobenzene spacer, such as p-phenylenediamine (PPD). The virtue of employing reversible imine bond formation [18] to clothe the LBT-H 2 2+ dication with two (CHO) 2 -DP24C8 units and two PPD spacers is that errors can be corrected [19] before the final structure is fixed by
