1,4-Diazabicyclo[2.2.2]octane-1,4-diium bis(3-chlorobenzoate)
نویسندگان
چکیده
In the title salt C6H14N2 (2+)·2C7H4ClO2 (-), two 3-chloro-benzoate (3CBA) anions are bridged by one diprotonated 1,4-di-aza-bicyclo-[2.2.2]octane-1,4-diium (H2DABCO(2+)) dication through N-H⋯O hydrogen bonds. In this way, a trimeric unit is generated, in which the mean planes of the two 3CBA anions are twisted with respect to each other by a dihedral angle of 59.87 (9)°. The trimeric units are linked into a three-dimensional network via weak C-H⋯O inter-actions.

The 1:1 co-crystallization of 1,4-di-aza-bicyclo-[2.2.2]octane (DABCO) with 4-nitro-benzoic acid in ethanol-water (3/1) gave the salt dihydrate C6H13N2 (+)·C7H4NO4 (-)·2H2O, (1), whereas from methanol, the salt C6H14N2 (2+)·2C7H4NO4 (-), (2), was isolated. In (1), the cation and anion are linked by a strong N-H⋯O hydrogen bond, and the carboxyl-ate anion is close to planar [dihedral angle betwe...

The title compound, [Co(C5H7O2)2(C6H12N2)] n , was obtained as a one-dimensional coordination polymer from bis-(acetyl-acetonato)di-aqua-cobalt(II), [Co(acac)2(OH2)2], and 1,4-di-aza-bicyclo-[2.2.2]octane (DABCO), a di-amine with good bridging ability and rod-like spacer function. In the chain complex that extends along the c axis, the Co(II) atom is six-coordinated, the O-donor atoms of the ch...

The title compound, C(6)H(14)N(2) (2+)·2C(7)H(4)ClO(2) (-), contains trimeric units linked by N-H⋯O hydrogen bonds. The carboxyl-ate groups of the 2-chloro-benzoate anions form dihedral angles of 66.1 (1) and 76.1 (1)° with the respective chloro-benzene rings to which they are bound. The hydrogen-bonded trimers are arranged in layers in the (200) planes and the chloro-benzoate anions form edge-...

In the title compound, (C(6)H(14)N(2))[Mg(H(2)O)(6)](SO(4))(2), the Mg(II) ion, lying on an inversion center, is coordinated by six water mol-ecules in a slightly distorted octa-hedral geometry. The 1,4-diazo-niabicyclo-[2.2.2]octane cation is located about a twofold rotation axis. Inter-molecular N-H⋯O and O-H⋯O hydrogen bonds link the cations and the anions into a three-dimensional network.
