Abstract
The structure of 1RS,4SR,7SR,10RS-(1,4,7,10-tetraazacyclopentadecane)copper(II) tetrachlorozincate, determined at 120 K, is reported: C11H26Cl4CuN4Zn, orthorhombic, P b c a (Hall−P 2ac 2ab); a, 14.0675(7); b, 14.4206(6); c, 18.2106(10) Å. The cation has approximate two-fold symmetry, with the CuN4 group tetrahedrally twisted, with NH groups alternating on opposite sides of the N4 group around the ring. The five-membered chelate rings have gauche conformations and the eight-membered chelate ring has an extended twist conformation. The anion and cation are linked into chains by hydrogen bonds and weak Cu···Cl interactions.
