The first 2D trinuclear Cd(II)-complex with adenine nucleobase: Hydrothermal synthesis, crystal structure and fluorescent properties

The first 2D aggregate, {[Cd-3(mu(3)-ade)(2)(ap)(2)(H2O)(2)]. 1.5H(2)O}(n) (1) (where adeH = adenine; H(2)ap = adipic acid), with trinuclear Cd(II) as secondary building units, has been successfully synthesized, the compound shows scarce coordination modes (tridentate mu 3-N3,N7,N9 for ade and hexadentate eta(1) :eta(2) :eta(2) :eta(1) for. exible ap) and a novel crystal packing arrangement, exhibiting strong fluorescent emission properties.
