Pyridine-borane complex was synthesized by reaction of pyridine with borane
-dimethyl sulfide complex. The pyridine-borane complex was used as a precur
sor for BCN alloy. The BCN alloy was fabricated by passing through a cross-
linked pyridine-borane derivative obtained From the pyridine-borane complex
by heating at 1273 K for 2 h in Ar. Turbostratic layered BCN alloy was pre
pared by the pyrolysis of the pyridine-borane derivative. Four coordination
number of boron which was remained in both the complex and the derivative
changed to three coordination number in the BCN ceramic alloy with a compos
ition of B2NC4 obtained. Lithium insertion into this B2NC4 alloy has been a
ttempted.
