Issue Date: | 2001 | Citation: | Journal of Chemical Crystallography. 31:3 (2001) 167-171 | Abstract: | [Cu2(bet)4Cl2]Cl2·4H2O (bet = betaine: IUPAC name: trimethylammonioacetate) is monoclinic, space group P21/c, a = 11.0510(10) Å, b = 14.7140(4) Å, c = 11.1620(15) Å, ß = 107.40(2)°. The dinuclear copper(II) cation [Cu2(bet)4Cl2]2+ is counterbalanced by two naked Cl- ions. The copper(II) ions have a square bipyramidal environment with oxygen atoms from the acetato groups in the basal planes and a chlorine and a copper atom occupying the apical positions. The metal atoms are µ2-bridged by four acetato groups and the molecular symmetry is close to C2h. The two symmetry-independent chelating betaine molecules are present in their zwitterionic, neutral form. | URI: | https://hdl.handle.net/10316/7694 | DOI: | 10.1023/A:1014319905435 | Rights: | openAccess |
