    • we use the abbreviations [BmR] and [TmR] to represent the bis(2-mercapto-l-alkylimidazolyl)borate and tris(2-mercapto-lalkylimidazolyl)borate ligands, respectively.
    • Bis- and tris-(pyrazolyl)hydroborato ligands are represented by the abbreviations [BpRR'J and [TpRR'], with the 3- and 5-alkyl substituents listed respectively as superscripts. A substituent (X) on boron other than hydrogen is listed as a prefix, i.e. [XBpRR'] and [XTpRR']. By analogy, we use the abbreviations [BmR] and [TmR] to represent the bis(2-mercapto-l-alkylimidazolyl)borate and tris(2-mercapto-lalkylimidazolyl)borate ligands, respectively.
