“…To our knowledge the only reports of open-framework metal succinates are those of cobalt, 10 nickel, 11 iron, 12 and manganese. 13 No open-framework metal succinate appears to have been synthesized in the presence of organic amines. We have attempted to prepare cadmium succinates with open architectures by employing different synthetic routes, one of them employing organic-amine succinates as a starting material.…”

Open-framework cadmium succinates, [CN(3)H(6)](2)[Cd(2)(C(4)H(4)O(4))(Cl)(2)], I; [CN(3)H(6)](2)[Cd(C(4)H(4)O(4))(2)], II; Cd(2)(C(4)H(4)O(4))(2)(C(4)N(2)H(8))(H(2)O)(3), III; [C(4)N(2)H(12)][Cd(2)(C(4)H(4)O(4))(3)].4H(2)O, IV; Cd(C(4)H(4)O(4))(H(2)O)(2), V; and Cd(3)(C(4)H(4)O(4))(2)(OH)(2)], VI, of different dimensionalities have been synthesized by hydrothermal procedure by employing two different strategies, one involving the reaction of Cd salts with organic-amine succinates and the other involving the hydrothermal reaction of Cd salts with a mixture of succinic acid and the organic amine. While the latter procedure yields structures without any amine in them, the former gives rise to amine templated cadmium succinates with open architectures. By employing guanidinium succinate we have obtained I and II, and with piperazinium succinate we obtained III and IV. Of these I has a one-dimensional chain structure, IV has a layered structure, and II and III have three-dimensional architectures. The two cadmium succinates without incorporation of amine, V and VI, possess layered and three-dimensional structures, respectively. The three-dimensional structures II and III exhibit interpenetration similar to that in diamondoid and alpha-polonium type structures, respectively.

Source of materialA suspension obtained by addition of 0.98 g (5.0 mmol) MnCb · 4H20,1.18 g (10.0 mmol) succinic acid and 1.32 g (23.6 mmol) KOH in 20 ml doubly distilled water was heated in a 50 ml Teflon-lined stainless steel vessel at 453 Κ for 5 days. After cooling, the solid was filtered out. The filtrate was firstly kept at room temperature for one month and then maintained at 323 K. Two days later, incarnadine crystals were formed and separated out. The final filtrate was allowed to stand at room temperature. On next day, nearly colorless crystals were grown and the successive X-ray diffraction analysis confirmed the triclinic Mn(C4H404) · DiscussionTwenty years ago, Gupta and coworkers reported the crystal structure of a triclinic manganese(II) succinate tetrahydrate, Mn(C4H4C>4) · 4H2O, from Weissenberg photographic X-ray diffraction data [1], but the hydrogen atoms were not located. To gain an insight into the difference between the triclinic and the monoclinic Mn(C4H404) · 4H2O [2], we refined the triclinic phase using more accurate diffraction data. In contrast to the monociinic modification, no intrachain hydrogen bonds are observed in the title succinate. Each ID chains in the title compound is hydrogen bonded to four neighboring chains whereas each ID chain in the monociinic phase is hydrogen bonded to six neighboring ones. The opposite rotation of both caiboxylate groups around the terminal C-C bonds breaks the strong intrachain hydrogen bonds in the monoclinic modification to form the ID chains in the title triclinic modification. This is accompanied by a reduction of the closest intrachain Mn-Mn separation through the succinate bridges from 9.907(1) Â to 8.980(1) Â.

“…As shown in Fig. 1, the Mn II center is six-coordinated by three carboxylate O atoms of three succ ligands, one water O atom and two pyridyl N atoms of bipy ligands, and displays slightly distorted MnO 4 N 2 octahedral coordination geometry (Table 1) (McCann et al, 1997;Fleck et al, 2000;Zheng et al, 2002;Xiang et al, 1998;Kim et al, 2001;Liu et al, 2001), and the Acta Cryst.

The polymeric title complex, [[Mn(C(4)H(4)O(4))(C(10)H(8)N(2))(H(2)O)].0.5C(10)H(8)N(2)](n), possesses a three-dimensional open-framework structure, with the solvate 4,4'-bipyridine (bipy) molecules, which lie around centers of inversion, clathrated in the channels of the framework. The Mn(II) center is surrounded by three succinate (succ) ligands, one water molecule and two bipy ligands, and displays a slightly distorted octahedral coordination environment, with cis angles ranging from 84.14 (12) to 96.56 (11) degrees. Each succ dianion coordinates to three Mn(II) atoms, thus acting as a bridging tridentate ligand; in turn, the Mn(II) atoms are bridged by three succ ligands, thus forming a two-dimensional Mn-succ sheet pillared by the bridging bipy ligands. Two hydrogen-bonding interactions, involving the water molecules and the carboxy O atoms of the succ ligands, are present in the crystal structure.
