| Abstract |
The gas-phase fragmentations of a series of arylimido derivatives of hexamolybdate [Mo6O18(NC6H5-nR n )]2- (2-10, where R = CH3, i-C3H7, OCH3, NO2; n = 1 or 2) versus the parent species [Mo6O19]2- (1) were systematically studied using electrospray tandem mass spectrometry (ESI). Fragmentation of 1 generates two molybdate fragments only, [Mo3O10]2- and [Mo4O13]2-, whereas decomposition of 2-10 went through two dissociation pathways in which path A generates a variety of molybdate fragments via breaking the Mo-N bond followed by the cleavages of the multiple Mo-O bonds, whereas path B produces a range of molybdate fragments with arylimido group via breaking the multiple Mo-O bonds on POM framework. Moreover, the presences of mixed-oxidation-state molybdate fragments are characteristic for the fragmentation. The gas-phase stability order obtained by energy-variable collision-induced dissociation (CID) experiment reveals that 2-10 are generally less stable than 1 and substitution on the benzene ring exerts a considerable effect on the stabilization of the hybrid clusters.

Attention Score in Context
This research output has an Altmetric Attention Score of 1. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 April 2018.
All research outputs
#20,663,600
of 25,382,440 outputs
Outputs from Journal of the American Society for Mass Spectrometry
#3,086
of 3,835 outputs
Outputs of similar age
#266,100
of 340,784 outputs
Outputs of similar age from Journal of the American Society for Mass Spectrometry
#65
of 85 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 10th percentile – i.e., 10% of other outputs scored the same or lower than it.
So far Altmetric has tracked 3,835 research outputs from this source. They receive a mean Attention Score of 3.8. This one is in the 10th percentile – i.e., 10% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 340,784 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 11th percentile – i.e., 11% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 85 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
