A novel 4-connected binodal Moganite net with three-fold interpenetration

•A new coordination polymer is reported.•An unprecedented Moganite net with three-fold interpenetration is reported.•An unusual coordination mode of N,N′-di(4-pyridyl)adipoamide is reported.•A highly rare Moganite net based on both metal and organic nodes is reported.

Reported here is a novel Cd(II) coordination polymer (namely [Cd(L1)0.5(ntd)]n (1), L1 = N,N′-di(4-pyridyl)adipoamide, H2ntd2 = 1,4-naphthalenedicarboxylic acid). Single-crystal X-ray diffraction reveals that the framework can be represented as metal/organic-binodal 4-connected Moganite net with three-fold interpenetration. Importantly, for the first time, an unusual coordination mode is observed for the acylamide ligand in such manner that every L1 ligand links four Cd(II) ions through two nitrogen atoms from two pyridine groups and two oxygen atoms from two acylamide groups.
