Abstract
Two iron compounds [Fe(m-NO2phtpy)2](ClO4)2 1 and [Fe(m-Clphtpy)2](ClO4)2 2 are synthesized and their structures are determined by single crystal X-ray diffraction. Crystal data for 1 are: orthorhombic, space group Pcca, a = 25.471(4) Å, b = 10.8182(18) Å, c = 14.682(2) Å, and Z = 4. Crystal data for 2 are: orthorhombic, space group Pnna, a = 14.521(2) Å, b = 23.980(4) Å, c = 23.142(4) Å, and Z = 8. The iron atoms are coordinated by six N atoms from two terpyridines in both compounds. These two compounds are all linked by hydrogen bonds with C as donor and O as acceptor into a 3D network for 1 and a 2D network for 2. If viewed along the c direction in 1 and the a direction in 2, both compounds show the ordered figure with terpyridine overlapped as a square and the phenyl rings overlapped as a rectangle or a square.
