Poly[[diaqua­(3-carb­oxy-5-nitro­ben­zo­ato)(μ-5-nitro­benzene-1,3-dicarboxyl­ato)neodymium(III)] 2.5-hydrate]

In the title compound, {[Nd(C(8)H(3)NO(6))(C(8)H(4)NO(6))(H(2)O)(2)]·2.5H(2)O}(n), the Nd(II) ion is nine-coordinated by seven O atoms from five carboxyl­ate groups and two water mol­ecules. The [Nd(C(8)H(3)NO(6))(H(2)O)(2)](2+) units are bridged by 5-nitro­isophthalate dianions, forming polymeric s...

Sumario:In the title compound, {[Nd(C(8)H(3)NO(6))(C(8)H(4)NO(6))(H(2)O)(2)]·2.5H(2)O}(n), the Nd(II) ion is nine-coordinated by seven O atoms from five carboxyl­ate groups and two water mol­ecules. The [Nd(C(8)H(3)NO(6))(H(2)O)(2)](2+) units are bridged by 5-nitro­isophthalate dianions, forming polymeric sheets parallel to the ab plane. The polymeric sheets are linked into a three-dimensional network by O—H⋯O and C—H⋯O hydrogen bonds, and π–π inter­actions [centroid–centroid distance = 3.5533 (11) Å]. The 5-nitro­isophthalate(1−) anion is disordered over three positions with an occupancy ratio of 0.68:0.23:0.09. Two of the uncoordinated water mol­ecules are disordered over two positions, with occupancy ratios of 0.722 (15):0.278 (15) and 0.279 (6):0.221 (6), respectively.
