1,4,10,16,21-Pentaaza-7,13,24-triazoniabicyclo­[8.8.8]hexacosane monohydrate clathrate trichloride hexahydrate

The title compound, C₁₈H₅₉N·3 Cl^-·7H₂O, is a chloride salt of a triprotonated cryptand. One of the water molecules is located inside the crypt and makes six hydrogen bonds to the crypt (two as donor and four as acceptor). The coordination geometry about the bound water molecule is trigonal prismatic.

Bis(2-pyridyl­methyl)­amine–borane

The title compound, C₁₂H₁₂N₃·BH₃ or C₁₂H₁₅BN₃, contains a BH₃ group and two picolyl groups attached to a central N atom. Both edge-to-face and face-to-face π-stacking interactions are found.

Penta­carbonyl­(N,N-dimethyl­benzyl­amine)tungsten

The title compound, [W(C₉H₁₃N)(CO)₅], was prepared by irradiation of W(CO)₆ in tetra­hydro­furan in the presence of N,N-dimethyl­benzyl­amine. The geometry at the W atom is approximately octa­hedral, with the cis bond angles in the range 86.3 (3)-95.6 (2)°. The bond to the tertiary amine is long [2.371 (5) Å] and, as might be expected, the bond to the trans carbonyl is quite short [W-C = 1.964 (7) Å]. The remaining W-CO bonds lie in the range 2.033 (6)-2.049 (6) Å. Similar bonding patterns have been observed in related W(CO)₅(amine) complexes,
