摘要：
The complex [Mn(salen)NCS] (H(2)salen = N,N'-ethylene bis(salicylideneiminato)) has been synthesized by the reaction of [Mn(salen)]ClO4.2H(2)O with KSCN. It crystallizes in space group Pbca, a = 12.453(1), b = 13.756(2), c = 18.777(1)Angstrom, V = 3216.6(16)Angstrom(3), Z = 8. X-ray structure analysis revealed a dimeric structure, in which two Mn (III) ions are bridged by two phenoxo oxygen atoms, O(2) and O(2A), of the salen ligand in an out-of-plane fashion with an Mn-O(2A) distance of 2.742(2)Angstrom. Each manganese atom has distorted octahedral coordination geometry. The thiocyanate ion coordinates to Mn(III) with the N-atom with Mn-N(3) equal to 2.160(2)Angstrom.
