| Popis: | [Zn(satnen)Br], where satnen = H 2 N(CH 2 ) 2 NH(CH 2 ) 3 -N=CHC 6 H 4 O − , is the first example of a complex containing a tretradentate Schiff base derived from 1,6-diamino-3-azahexane. The Zn atom is bonded to five atoms (Br, O and three N atoms) and its coordination polyhedron can be described either as a distorted trigonal bipyramid (the Br atom being situated in the equatorial plane) or as a distorted tetragonal pyramid (with the Br atom at the apex). The Zn-Br bond is unusually long [2.4812 (7) A]. The bonding distances within the phenyl ring vary between 1.34 (2) and 1.42 (1) A. The longer distances involve those C atoms which are connected either to O or to the C(H)=N− fragment. There are two intermolecular N−H...X,X = Br, O, hydrogen bonds; the X = O bond is extremely weak |
