What are people’s expectations of interracial political coalitions? This research reveals expectations of flexible interracial coalitions stemming from how policies and racial groups are viewed in terms of perceived status and foreignness. For policies seen as changing societal status (e.g., welfare), people expected Black–Hispanic political coalitions and viewed Asian Americans as more likely to align with Whites than with other minorities. For policies seen as impacting American identity (e.g., immigration), people expected Asian–Hispanic coalitions and that Black Americans would align with Whites more than other minorities. Manipulating a novel group’s alleged status and cultural assimilation influenced coalitional expectations, providing evidence of causality. These expectations appear to better reflect stereotypes than groups’ actual average policy attitudes and voting behavior. Yet these beliefs may have implications for a diversifying electorate as White Americans strategically amplified the political voice of a racial group expected to agree with their personal preferences on stereotyped policies. 

Since the discovery of the B 40 borospherene, research interests have been directed to the structural evolution of even larger boron clusters. An interesting question concerns if the borospherene cages persist in larger boron clusters like the fullerenes. Here we report a photoelectron spectroscopy (PES) and computational study on the structures and bonding of B 41 − and B 42 − , the largest boron clusters characterized experimentally thus far. The PE spectra of both clusters display broad and complicated features, suggesting the existence of multiple low-lying isomers. Global minimum searches for B 41 − reveal three low-lying isomers ( I–III ), which are all related to the planar B 40 − structure. Isomer II ( C s , 1 A′) possessing a double hexagonal vacancy is found to agree well with the experiment, while isomers I ( C s , 3 A′′) and III ( C s , 1 A′) both with a single hexagonal vacancy are also present as minor isomers in the experiment. The potential landscape of B 42 − is found to be much more complicated with numerous low-lying isomers ( VII–XII ). The quasi-planar structure VIII ( C 1 , 2 A) containing a double hexagonal vacancy is found to make major contributions to the observed PE spectrum of B 42 − , while the other low-lying isomers may also be present to give rise to a complicated spectral pattern. Chemical bonding analyses show isomer II of B 41 − ( C s , 1 A′) and isomer VIII of B 42 − ( C 1 , 2 A) are π aromatic, analogous to that in the polycyclic aromatic hydrocarbon C 27 H 13 + ( C 2v , 1 A 1 ). Borospherene cage isomers are also found for both B 41 − and B 42 − in the global minimum searches, but they are much higher energy isomers.
