[N(C4H9)(4)](2)[B10H10] reacts with 2-aminopyridine forming a product
mixture from which [2,9-(N,N'-(2-NH-(C5H4N))]B10H8](-) can be isolated
by ion exchange chromatography on diethylaminoethyl(DEAE) cellulose.
The crystal structure of [P(C6H5)(4)][2,9-(N,N'(2-NH-(C5H4N))]B10H8] (
triclinic, space group P1, a=10.1103(9), b=11.5665(9), c=14.877(2) Ang
strom, alpha=102.600(8), beta=107.567(8) und gamma = 96.487(7)degrees,
Z = 2) reveals the bonding of 2-NH2-(C5H4N) via both N atoms to vicin
al B atoms of the two square planes of the B-10 cluster (B2-N1=1.541(7
) und B9-N2=1.505(7) Angstrom) forming a five-membered ring.
