Two new rhenium(IV) mononuclear compounds of formula NBu 4[ReBr 4(OCN)(DMF)] ( 1) and (NBu 4) 2[ReBr(OCN) 2(NCO) 3] ( 2) (NBu 4 = tetrabutylammonium cation, OCN = O-bonded cyanate anion, NCO = N-bonded cyanate anion and DMF = N, N-dimethylformamide) have been synthesized...
The lowest energy fragmentation process in both OC-NCO+ and OC-NCS+ is C-N bond cleavage but the strength of these bonds is significantly different. They are estimated from surface-induced dissociation data taken as a function of collision energy (energy resolved mass spectra) to be 4 and 3...
