Synthesis and Crystal Structure of [Ni(phen) (dipic)H2O].4H2O

The new dipicolinate complex of nickel, [Ni(phen) (dipic)H2O].4H2O has been prepared where dipic is dipicolinate or pyridine- 2,6-dicarboxylate and phen is1,10phenanthroline. The crystal structure was determined by single-crystal X-ray diffraction. This complex crystallized in the triclinic system, with space group Pī, a=7.9131(4)Å, b= 10.6006(6) Å, c=13.2268(7) Å, β= 96.158(1)°, V= 1027.55(10) Å3, Z= 2. The final R value is 0.0340 for 4677 measured reflections.
