N,N'-Propylenedioxybis(2,4,6-trimethylbenzenesulfonamide): molecules of unexpected conformation form a molecular ladder built from two independent N-H...O=S hydrogen bonds.

Molecules of the title compound, C(21)H(30)N(2)O(6)S(2), adopt a skeletal conformation which does not possess even approximate internal symmetry. The molecules are linked by two N-H...O=S hydrogen bonds [H...O = 1.97 A (x2), N...O = 2.865 (2) and 2.864 (2) A, and N-H...O = 160 and 159 degrees] into molecular ladders, alternatively described as chains of edge-fused R(2)(2)(20) rings.

Bis(acetonitrile-kappaN)[(1RS,4RS,8SR,11SR)-1,4,8,11-tetraazatetradecane-kappa(4)N]copper(II) bis[tetrakis[3,5-bis(trifluoromethyl)phenyl]borate] 0.31-hydrate.

The title compound, [Cu(C(2)H(3)N)(2)(C(10)H(24)N(4))](C(32)H(12)BF(24))(2).0.31H(2)O, crystallizes as an ionic species with no interactions between the ions. The [Cu(II)(cyclam)(MeCN)(2)](2+) dication (cyclam is 1,4,8,11-tetraazatetradecane), located on a 2/m symmetry site, forms as a distorted octahedral species with four Cu-N(cyclam) bonds of 2.013 (2) A and two C-N(MeCN) bonds of 2.499 (4) A. The [B[C(6)H(3)(CF(3))-3,5](4)](-) anion, located on a twofold axis, is a distorted octahedral species. A small amount of water is present, occupying sites between columns of ions.
