Silane (Silicane) is an inorganic compound with chemical formula SiH 4. It is a colorless, pyrophoric gas with a sharp, repulsive, pungent smell, somewhat similar to that of acetic acid . [ 6 ] Silane is of practical interest as a precursor to elemental silicon .
Another example is O(SiH 3) 2 with an Si–O–Si angle of 144.1°, which compares to the angles in Cl 2 O (110.9°), (CH 3) 2 O (111.7°), and N(CH 3) 3 (110.9°). [24] Gillespie and Robinson rationalize the Si–O–Si bond angle based on the observed ability of a ligand's lone pair to most greatly repel other electron pairs when the ligand ...
SIH is typically secondary to a spontaneous spinal CSF leak. [ 17 ] [ 14 ] Cranial CSF leaks do not cause SIH. [ 19 ] While this symptom can be referred to as intracranial hypotension , the intracranial pressure may be normal, with the underlying issue instead being low CSF volume, in this case a sCSFL may be referred to as CSF hypovolemia .
