Notes:
The cluster 11B and 1H NMR chemical shifts of the known arsenaborane species [7-Me-nido-7-AsB10H12], [7-Me-nido-7-AsB10H11]-, [nido-7-AsB10H12]-, [closo-1,2-As2B10H10] and [nido-7,8-As2B9H10]-, of the known stibaborane species [closo-1,2-Sb2B10H10] and [closo-1,2-CSbB10H11], and of the previously unreported metalladiarsenaboranes [3,3-(PPh3)2-3-(H)-closo-3,1,2-RhAs2B9H9] and [3-(η5-C5Me5)-closo-3,1,2-RhAs2B9H9] were measured and assigned by [11B-11B]-COSY, [1H-1H]-COSY-{11B}, and 1H-{11B} NMR experiments. Similarities and trends in the cluster shielding patterns were examined in order to assess changes in supposed electronic structures.
