Coexistence of a pair of enantiomorphic forms of chiral quartz nets with an interpenetrating mode in a centrosymmetric coordination polymer†
Abstract
2-Fold interpenetrating chiral quartz nets with opposite handedness have been observed in a centrosymmetric coordination polymer {[Zn3(bmzbc)6]ยท11.5DMF}n (Hbmzbc = 4-(benzimidazole-1-yl)benzoic acid), which is a unique example of an interpenetrating enantiomorphic pair of quartz nets that have never been realized before.
