Globally scalable sunlight-driven devices that convert solar energy into storable fuels will require efficient light absorbers that are made of non-precious elements. Suitable photoanode materials are yet to be discovered. Here we utilised the timesaving nature of pulsed-laser-in-liquids synthesis and

The intermediate [Cd(4-PTZ)(2)(H(2)O)(4)] [4-PTZ is 5-(4-pyridyl N-oxide)tetrazolate, C(6)H(4)N(5)O], (I), in the synthesis of 4-HPTZ, (II), from the cycloaddition reaction of 4-cyanopyridine N-oxide with NaN(3) in water using CdCl(2) as catalyst, was structurally characterized. The unique Cd atom lies on a
