STRUCTURES OF TETRAKIS(2-AMINO-6-METHYLPYRIDINIUM) CATENA-BIS(ACETONITRILE)-TETRADECA-MU-CHLORO-PENTANICKELATE(II) AND BIS(3-PICOLINIUM) CATENA-DIAQUAOCTA-MU-CHLORO-TRINICKELATE(II)

4C6H9N2+.[Ni5Cl14(C2H3N)2]4-, (I), M(r) = 1308.6, triclinic, P1BAR, a = 8.686 (1), b = 12.483 (2), c = 12.933 (2) angstrom, alpha = 73.09 (1), beta = 73.65 (1), gamma = 70.87 (1)degrees, V = 1240.4 (3) angstrom3, Z = 1, D(x) = 1.75 Mg m-3, lambda(Mo Kalpha) = 0.71069 angstrom, graphite monochromator, mu = 2.670 mm-1, F(000) = 658, T = 295 K, 259 parameters refined to R = 0.0591 and wR = 0.0399 for 1506 unique observed [F greater-than-or-equal-to 3 sigma(F)] reflections. 2C6H8N+.[Ni3Cl8(H2O)2]2-, (II), M(r) = 684.0, triclinic, P1BAR, a = 7.648 (1), b = 8.498 (1), c = 9.550 (1) angstrom, alpha = 85.15 (1), beta = 83.71 (1), gamma = 69.08 (1)degrees, V = 575.6 (2) angstrom3, Z = 1, D(x) = 1.97 Mg m-3, lambda(Mo Kalpha) = 0.71069 angstrom, graphite monochromator, mu = 3.393 mm-1, F(000) = 343, T = 295 K, 132 parameters refined to R = 0.0246 and wR = 0.0339 for 2177 unique observed [F greater-than-or-equal-to 3 sigma(F)] reflections. Both structures are built up from [NinCl3n+1L2] oligomers which contain face-sharing NiCl6 octahedra and are capped on both ends by NiCl5L octahedra. Di-mu-chloride bridges link these oligomers together into the non-uniform chains characteristic of this new An-1[NinCl3n-1L2]L2] family.
