A monoclinic polymorph of (R,R)-4,4'-dibromo-2,2'-[cyclo-hexane-1,2-diylbis(nitrilo-methanylyl-idene)]diphenol.

Project description:The title compound, C(20)H(20)Br(2)N(2)O(2), a tetra-dentate Schiff base, is the enanti-omerically pure R,R-diastereomer of four possible stereoisomers. The mol-ecular structure reveals two strong intra-molecular O-H⋯N hydrogen bonds between the hy-droxy O atom and the imino N atom, which each generate S(6) rings. In the crystal, mol-ecules are stacked in columns along the a axis; when viewed down the b axis, successive columns are stacked in the opposite direction. The structure reported herein is the monoclinic polymorph of the previously reported ortho-rhom-bic form [Yi & Hu (2009 ▶). Acta Cryst. E65, o2643], in which the complete mol-ecule is generated by a crystallographic twofold axis.

Redetermination of 6,6'-dimeth-oxy-2,2'-[hexane-1,6-diylbis(nitrilo-dimethyl-idyne)]diphenol.

Project description:The title compound, C(22)H(28)N(2)O(4), contains two independent centrosymmetric mol-ecules (A and B). In the previous structure determination [Xia et al. (2007 ?). Acta Cryst. E63, o259] both A and B were modelled as neutral mol-ecules with the H atoms of the the O-H groups included in calculated positions. In this redetermination, the transferrable H atoms were located in difference maps and freely refined, indicating that one mol-ecule (A) crystallizes in the neutral (nonzwitterionic) form and the other in the zwitterionic form, namely 6,6'-dimeth-oxy-2,2'-[hexane-1,6-diylbis(nitrilo-dimethyl-idyne)]-di-phenol-6,6'-dimeth-oxy-2,2'-[hexane-1,6-diylbis(nitrilio-di-methyl-idyne)]diphenolate (1/1). This finding is supported by significant differences in the C-O(H) (A) and C-O(-) (B) bond lengths. In the crystal, the zwitterionic mol-ecules (B) are involved in inter-molecular N-H?O hydrogen bonds forming one-dimensional chains along [001]. Each independent mol-ecule forms an intra-molecular O-H?N (A) or N-H?O (B) hydrogen bond. In mol-ecule B, one of the -CH(2)- groups is disordered over two sets of sites with refined occupancies of 0.659?(8) and 0.341?(8).
