In the coordination polymer, {[Pr(C(6)H(5)O(7))(H(2)O)(2)]·H(2)O}(n), seven of the nine coordination sites of the monocapped square-anti-prismatic geometry are occupied by three O atoms of the same citrate trianion (an O atom of the hy-droxy unit and the formally single-bond O atoms from two carboxyl units). Two other coordination sites are occupied by the O atoms of a chelating carboxyl unit of another citrate; one of these atoms is additionally involved in bridging. The seventh coordination si ...[more]
