的集群B-11和H - NMR化学位移已知arsenaborane物种[7-Me-nido-7-AsB10H12], [7-Me-nido-7-AsB10H11], [nido-7-AsB10H12], [closo-1, 2-As2B10H10]和[nido-7 8-As2B9H10],已知stibaborane物种[closo-1, 2-Sb2B10H10]和[closo-1 2-CSbB10H11],和先前的报道metalladiarsenaboranes [3 3 - (PPh3) 2 - 3 (H) -closo-3, 1, 2-RhAs2B9H9]和[3 - (eta-5-C5Me5) -closo-3 1 2-RhAs2B9H9)测量和交办B-11-B-11舒适,H-1-H-1舒适——{B-11},H-1-{B-11}核磁共振实验。研究了簇屏蔽模式的相似性和趋势，以评估假想电子结构的变化。
The cluster B-11 and H-1 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-(eta-5-C5Me5)-closo-3,1,2-RhAs2B9H9] were measured and assigned by [B-11-B-11]-COSY, [H-1-H-1]-COSY-{B-11}, and H-1-{B-11} NMR experiments. Similarities and trends in the cluster shielding patterns were examined in order to assess changes in supposed electronic structures.
