Two cadmium coordination polymers showing three-fold interpenetrated and self-catenated three-dimensional networks

• A three-fold interpenetrated 3D distorted diamondoid network.
• A 6-connected self-catenated 3D network.
• The flexible 1,4-bis(2-methyl-imidazol-1-ylmethyl)benzene.
• The effect of the multicarboxylate fumarate and glutarate.
• The luminescence and thermal stability.

The hydrothermal reaction of CdCl2, 1,4-bis(2-methyl-imidazol-l-ylmethyl)benzene (bix) and fumarate (fum) or glutarate (glu) gives two unusual coordination polymers {[Cd2(bix)2(fum)Cl2]·0.5H2O}n (1) and [Cd2(bix)(glu)2]n (2). 1 shows a three-fold interpenetrated three-dimensional distorted diamondoid network with different length three ligands. 2 displays a 6-connected self-catenated three-dimensional network with the point symbol of (44
