摘要
[MPy4(N-3)(2)]. 2Py(M=Ni, Co) are clathrates where two of six pyridine species are included in the crystal structure of the host complex without chemical bonding. The clathrates are isostructural, orthorhombic, space group Pnna(52), Z=4. For the Ni compound a = 14.958(5), b = 11.909(5), c = 17.517(7) Angstrom, V = 3120(2) Angstrom(3), mu = 12.25 cm(-1), final R = 0.057. The Cocompound is of very similar structure (a = 14.980(3), b=11.980(2), c = 17.350(5) Angstrom, V = 3114(1) Angstrom(3), mu = 46.50 cm(-1)). The metal cation in the host molecule is surrounded by six donor nitrogens of two terminal azido-groups in trans-positions and four pyridine ligands. The complex molecule lies on a twofold axis parallel to a.
