M 2 (H 2 O)[μ 10 ‐C 6 H 2 (COO) 4 ] ( M = Ba 2+ , Pb 2+ ) – Two Isotypic Three‐Dimensional Coordination Polymers with a Layer‐like Separation between Anions and Cations
Monoclinic single crystals of Ba 2 (H 2 O)[μ 10 ‐C 6 H 2 (COO) 4 ] ( 1 ) and Pb 2 (H 2 O)[μ 10 ‐C 6 H 2 (COO) 4 ] ( 2 ) were obtained using the silica gel method [space group C 2/ c (no. 15), Z = 4; 1 : a = 780.89(4), b = 1756.19(8), c = 914.80(5) pm, β = 114.512(5)°; 2 : a = 756.70(10), b = 1772.8(...

ions (

M
(1) is surrounded by eight carboxylate oxygen atoms and one water molecule forming a tricapped trigonal prism.
M
(2) is coordinated by ten carboxylate oxygen atoms in the shape of a tetracapped octahedron. The connection between the
M
(1) and
M
(2) polyhedra leads to infinite layers parallel to (010), which are linked by [C
