A new dabco-templated metal sulfate: 1,4-diazoniabicyclo[2.2.2]octane hexaaquacadmium bis(sulfate)

چکیده
The title double mol-ecular salt, (C(6)H(14)N(2))[Cd(H(2)O)(6)](SO(4))(2), is an isostructure of its Mn and Co analogues. The Cd(II) atom adopts a near-regular CdO(6) octa-hedral coordination geometry. The crystal structure can be described as an alternation of cationic and anionic layers along [010], and numerous O-H⋯O and N-H⋯O hydrogen bonds are observed. No thermal anomalies corresponding to possible phase transitions were observed in DSC (differential scanning calorimetry) measurements and the 93 K structure is almost the same as the room-temperature structure.

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.
