In its coordination complexes, the borohydride ion is bound to the metal by means of one to three bridging hydrogen atoms. [9][3][10] In most such compounds, the [BH4]− ligand is bidentate. …

2005年1月3日 · In all isomers studied here, the charge is transferred from BH 4 ligand (which is the electron donor through σ-bonding electron pair of B–H) to central metal, but also the CO …

Metrical characterization of tridentate tetrahydroborate ligation to a transition-metal ion. Structure and bonding in Hf(BH4)4 by single-crystal neutron diffraction. Robert W. Broach; I Ssuer …

In all complexes, in solution the borohydride ligand undergoes rapid internal motion, with all four boron-bound hydrogens interchanging environments. The barriers for BH 4 reorientation …

The stability of the BH 4 − ligand is influenced by both the coordination mode and the nature of the metal centre. The BH 3 species is released more easily from complexes with less electron …

1991年11月1日 · Theoretical study on interaction of different coordination modes of BH4 ligand with transition metal in [TM(BH4)(CO)4]− (TM=Cr, Mo). Journal of Organometallic Chemistry …

The η2-coordination of BH4– is confirmed by the infrared and Raman spectroscopies. The title compound is the first aluminum-based borohydride complex not stabilized by halide anions or …

1995年7月1日 · Theoretical study on interaction of different coordination modes of BH4 ligand with transition metal in [TM(BH4)(CO)4]− (TM=Cr, Mo). Journal of Organometallic Chemistry …

This contribution reviews the structural and dynamical properties of mononuclear transition metal complexes with tetrahydroborate ligands. Three different coordination modes involving one …

2019年4月16日 · The main findings of this study are that (1) IP 3 R1 inhibition by the anti-apoptotic Bcl-2 protein is modulated by the ligand, IP 3, and thus by the level of IP 3 R activity; …
