Synthesis, characterization, and crystal structure of a 3D coordination polymer [Cd₂·(H₃C₉N₁₂)·Cl·(H₂O)₂]

ABSTRACT

A new Cd(II) coordination polymer has been prepared by solvothermal synthesis and characterized by single-crystal X-ray diffraction, IR, and element analysis. Complex [Cd₂·BTT·Cl·(H₂O)₂]_n (1) [H₃BTT = 1,3,5-tris(2H-tetrazol-5-yl)benzene] is monoclinic, space group P2₁7sol;c with a = 10.601(11) Å, b = 15.5428(16) Å, c = 9.0083(9) Å, β = 106.117(3)°, V = 1426.0(3) ų. The final refinment gave R = 0.0192, and wR = 0.0473 for reflections with I > 2σ(I). Single-crystal X-ray diffraction analysis reveals that the compound 1 is a novel three-dimensional framework, featuring three types of connections of the tetrazole ring.
