Two novel pillared-layer lanthanide borates built by Ln@B12O28/29 ring clusters and dicarboxylate linkers (Ln = Pr, Nd). Issue 29 (22nd June 2016) - Li, Lei-Lei
Abstract : Two unusual organic–inorganic hybrid pillared-layer lanthanide borates with two types of Ln-centered ring clusters, Ln@B12 O28 and Ln@B12 O29, have been made. Abstract : Two organic–inorganic hybrid pillared-layer lanthanide borates, [Ln2 B8 O12 (bdc)3 (H2 O)]·H2 O (Ln = Pr, 1 ; Nd, 2 ; H2 bdc = 1, 4-benzene dicarboxylic acid), have been made, in which inorganic layers are built by Ln-centred oxoboron ring clusters, Ln@B12 O28 /Ln@B12 O29, while the pillars are organic bdc linkers. Interestingly, two types of linkages, Ln–O–C and B–O–C bonds, exist in the structures, showing firstly novel linking modes between inorganic polyborate and organic dicarboxylate.
