Thermal properties of Zn(2)(C(8)H(4)O(4))(2)•C(6)H(12)N(2) metal-organic framework compound and mirror symmetry violation of dabco molecules

Thermal properties of Zn(2)(C(8)H(4)O(4))(2)•C(6)H(12)N(2) metal-organic framework compound at 8–300 K suggest the possibility of subbarrier tunnelling transitions between left-twisted (S) and right-twisted (R) forms of C(6)H(12)N(2) dabco molecules with D(3) point symmetry. The data agree with thos...

description Thermal properties of Zn(2)(C(8)H(4)O(4))(2)•C(6)H(12)N(2) metal-organic framework compound at 8–300 K suggest the possibility of subbarrier tunnelling transitions between left-twisted (S) and right-twisted (R) forms of C(6)H(12)N(2) dabco molecules with D(3) point symmetry. The data agree with those obtained for the temperature behavior of nuclear spin-lattice relaxation times. It is shown that there is a temperature range where the transitions are stopped. Therefore, Zn(2)(C(8)H(4)O(4))(2)•C(6)H(12)N(2) and related compounds are interesting objects to study the effect of spontaneous mirror-symmetry breaking and stabilization of chiral isomeric molecules in solids at low temperatures.
