Abstract
A new syn-mer-cis(N * ) -[Co (3, 3-tri) (ibn) Cl] [ZnCl4]. 2H2O(here 3, 3-tri = N- (3-Aminopr opyl) -1, 3-propanediamine; ibn = 1, 2 - diamino-2 - methylpropane ) isomer was synthesised by decomposing corresponding per-oxide complex. The crystal structure was determined by Rigaku AFC 7R. It belongs to triclinic with space group P 1(#2), a = 99. 58(2) nm, b = 114. 83(2) nm, c = 98. 81 (1 ) nm, a = 96. 79(2), =97. 243(10), 96. 89(1), v= 1. 1055(3) x 106nm3, Dc = 1. 678g cm-3, Z = 2, F000 = 572. 00, u(MoKa) = 24. 59cm- 1, R = 0. 025, Rw=0. 034. There are two complex cations, two [ZnCl4] 2- anions and four H2O molecules in a unit cell. The complex canon consists the cobalt atom surrounded by one chlorine atom and five nitrogen atoms in an approximated octahedral configuration, the see-NH proton is closed to the coordinated chlorine atom (syn-) and the nitrogen atom of the ibn which is adjacent to the methyl substituted carbon atom (cis (N* ) ).
