Tetra-kis(μ-3-aza-niumylbenzoato)-κO:O,O';κO,O':O;κO:O'-bis-[tetra-aqua-neodymium(III)] hexa-chloride tetra-hydrate.

ABSTRACT: The structure of the title compound, [Nd(2)(C(7)H(7)NO(2))(4)(H(2)O)(8)]Cl(6)·4H(2)O, consists of dimeric cationic units related by an inversion centre. The two Nd(III) atoms are linked by two bridging bidentate carboxyl-ate groups and two bidentate chelating bridging carboxyl-ate groups, with an Nd⋯Nd separation of 4.1259 (4) Å. Each Nd(III) atom is nine-coordin-ated by five O atoms from the carboxyl-ate groups of the zwitterionic azaniumylbenzoate ligands and four from water mol-ecules. They adopt a distorted tricapped trigonal-prismatic arrangement. The dihedral angle between the mean planes of the benzene ring and the carboxlate groups are 7.7 (6) and 24.4 (5)°. The two carboxyl-ate groups are almost perpendicular to one another with a dihedral angle of 84.0 (7)°, while the two benzene
