title: The first three-fold interpenetrated framework with two different four-connected uniform nets of 6(6) dia and new chiral 8(6) mdf networks.
abstract: Two three-fold interpenetrated frameworks, [LnCuL(4)][Ln(0.25)Cu(0.25)L] (Ln = Dy 1, Er 2; HL = 4-(pyridin-4-yl)benzoic acid), have been made. Their structures contain two kinds of four-connected uniform nets: dia and mdf nets. The mdf net is a new chiral 8(6) net with the long vertex symbol (8(1).8(3).8(4).8(4).8(4).8(4)).
