However, the controlled synthesis of cyclic aggregates with precise size, achieved by modulating the oligomerization of fundamental building blocks (BBs), remains a formidable challenge. Here we report the synthesis of the previously elusive octameric member of molybdenum blue (MB) wheels, {Mo85} ( 1) and its dimer analogue {Mo172} ( 2), under the direction of novel BBs of {Mo1}, {Mo2} and bent {Mo6} pentagon. The combination of these with existing BBs facilitates wheel contraction and distortion, resulting in the formation of an ellipitical and half-closed {Mo85} octamer, the smallest cyclic cluster in MB family. The {Mo172} dimer exhibits cross-shaped architecture, composed of two {Mo86} clusters structurally analogous to {Mo85}. Moreover, the structural integrity of 1 and 2 was confirmed by mass spectrometry and other analytic techniques, enabling their exploration in photothermal conversion in both solution and solid-state.
