The phrase "a unique dataset of" is correct and usable in written English.
You can use it when referring to a specific collection of data that is distinct or one-of-a-kind in some way.
Example: "The researchers compiled a unique dataset of climate change indicators to analyze trends over the past century."
Alternatives: "an exclusive collection of" or "a distinctive set of".
Our empirical analysis is based on a unique dataset of 1000 firms publicly-traded in six European countries (France, Germany, Italy, Norway, Sweden and the UK).
Using a unique dataset of German research units, this paper deals with the influence that NPM mechanisms have on research performance.
By analyzing a unique dataset of newly founded Korean manufacturing firms, we find that the effects of the factors influencing firm survival differ substantially across technological regimes.
We leveraged a unique dataset of ecological and social information about tree-planting neighborhoods and matched comparison (non-tree planting) neighborhoods (total neighborhoods = 197; total survey respondents = 1551).
We test the model predictions on a unique dataset of Spanish small and medium size firms that contains information on worker self-reported importance of teamwork.
This study presents an analysis of a unique dataset of 4971 energy audits performed on homes in Austin, Texas in 2009 2010.
Using a unique dataset on the distribution of non-volant small mammals across replicate landscapes in the Atlantic forest of Brazil, we found strong evidence for our model predictions - that patch-area effects are evident only at intermediate levels of total forest cover, where landscape diversity is still high and opportunities for enhancing biodiversity through local management are greatest.
This paper provides a unique dataset on serum levels of activin A and B, and follistatin in critically ill patients, had ARF, and were in the ICU.

In particular, Software-type Wave Particle Interaction Analyzer (SWPIA) (Katoh et al. 2013; Hikishima et al. 2014) on board the ERG satellite will provide instantaneous wave and particle data measured in the chorus generation region with the extremely high time resolution less than the electron gyroperiod, which is a unique dataset for the investigation of nonlinear wave particle interactions.
In conclusion, we have argued that the epidemic models needed to answer policy questions can seldom be informed by a single source of information, and that the favourable scenario of a unique dataset for any given model parameter is unrealistic.
