Crystal structure of Pb3(IO4(OH)2)2.

Weil M - Acta Crystallogr Sect E Struct Rep Online (2014)

Bottom Line: Each of the Pb(2+) cations is surrounded by eight O atoms (cut-off value = 3.1 Å) in the form of a distorted polyhedron.The octa-hedral IO4(OH)2 (3-) anions are arranged in rows extending parallel to [021], forming a distorted hexa-gonal rod packing.The cations and anions are linked into a framework structure.

ABSTRACT
The structure of the title compound, trilead(II) bis-[di-hydroxido-tetra-oxido-iodate(VII)], was determined from a crystal twinned by non-merohedry with two twin domains present [twin fraction 0.73 (1):0.27 (1)]. It contains three Pb(2+) cations and two IO4(OH)2 (3-) anions in the asymmetric unit. Each of the Pb(2+) cations is surrounded by eight O atoms (cut-off value = 3.1 Å) in the form of a distorted polyhedron. The octa-hedral IO4(OH)2 (3-) anions are arranged in rows extending parallel to [021], forming a distorted hexa-gonal rod packing. The cations and anions are linked into a framework structure. Although H-atom positions could not be located, O⋯O distances suggest medium-strength hydrogen-bonding inter-actions between the IO4(OH)2 octa-hedra, further consolidating the crystal packing.

The crystal structure of Pb3(IO4(OH)2)2 in a projection along [021]. Displacement ellipsoids are drawn at the 90% probability level. O atoms bearing the OH function are given in green, the other O atoms are white. Pb—O bonds are omitted for clarity; hydrogen-bonding inter­actions are shown as green dashed lines.

O atoms bearing the OH function are given in green, the other O atoms are white. Pb—O bonds are omitted for clarity; hydrogen-bonding inter­actions are shown as green dashed lines.

Mentions: Three Pb2+ cations and two IO4(OH)23− octa­hedra are present in the asymmetric unit. The anions form a slightly distorted hexa­gonal rod packing with the rods extending parallel to [021]. Cations and anions are linked through common oxygen atoms into a framework structure (Fig. 1 ▶).
