Abstract
PMR linewidths (Delta nu) and spin-lattice relaxation times (T-1) were measured on [M(1-n-propyl-1H-tetrazole)(6)](BF4)(2) (M is Zn or Fe). Three motional minima of T-1 associated with steps of Delta nu were fo und, and a structural change in the temperature region of 100 to 120 K is suggested in the zinc complex. The spin transition temperature was found to be similar to 130 K, and an anomalous minimum of T-1 occurre d at 9 K in the iron complex. (C) 1997 Elsevier Science B.V.
