    • note
    • EDS was performed on several crystals of the compound by using 8 KV accelerating voltage and 120 s acquisition time and indicated that boron and silicon were present in the amber plate crystals; the ratio of boron to silicon was approximately 2.4:1. Samples were mounted on silver paste to obtain a clear carbon content. Measurements were performed with a JEOL JSM-35C scanning electron microscope equipped with a Noran Vantage Energy Dispersive Spectroscopy (Si:Li) detector and Norvar window suitable for the standardless quantitation of light elements (Z ≥ 4).

    • note
    • Band-structure calculations were performed by using the self-consistent full-potential linearized augmented plane-wave method (LAPW) within density functional theory (DFT) by using the generalized gradient approximation (GGA) for the exchange and correlation potential. Scalar relativistic corrections were added and spin-orbit interaction (SOI) was incorporated by using a second variational procedure. The calculations were performed with the WIEN97 program.
