摘要：

A heterometallic assembly, [Mn(salen)](2)[Ni(CN)(4)] . 1/2H(2)O (where salen=N, N'-ethylene-bis(salicylideneiminato)-dianion), has been prepared from the reaction of [Mn(salen)H2O]ClO4 . H2O with K-2[Ni(CN)(4)] . H2O in methanol/water. The compound crystallizes in the tetragonal space group P 4/ncc with the cell dimensions of a=14.604(2) Angstrom, c=16.949(3) Angstrom, and Z=4. The compound assumes a two-dimensional distorted square network structure, formed from Ni-CN-Mn(salen)-NC-Ni linkages with dimensions of Ni-C=1.867(7) Angstrom, Mn-N=2.312(6) Angstrom, Mn-N-C=163.8(6)degrees Ni-C-N=178.4(6)degrees. The two metal atoms Ni(II) and Mn(III) have square and slightly distorted octahedral arrangements, respectively. Magnetic susceptibility measurements indicate the presence of an intramolecular antiferromagnetic interaction and gives a Mn-Mn exchange integral of -3.2 cm(-1).
