Solvothermal Synthesis, Crystal Structures, and Photocatalytic Properties of Iodoplumbate Hybrids with Nickel(II) Complex Templates

“…The Pb(1) 2+ and Pb(2) 2+ ions are coordinated to six iodide anions at distances in the range of 3.0926(11)–3.3657(9) Å, forming PbI 6 octahedral primary building units (PBUs), with I–Pb–I angles in the range of 81.07(2)–180.00(2)° (Table S1). The bond lengths and angles of PbI 6 octahedra are correspondingly consistent with those observed in other iodoplumbates constructed by PbI 6 PBUs . Two Pb(1)I 6 and one Pb(2)I 6 PBUs are connected via face‐sharing (containing I1, I2 and I3), forming an asymmetric structural unit Pb 3 I 12 , which can be viewed as the secondary building unit (SBU) (Figure b).…”

“…In the case of lead iodine, a series of iodoplumbates have been synthesized using various organic cations as SDAs. The examples include [PbI 3 ] – , [Pb 2 I 6 ] 2– , [Pb 3 I 8 ] 2– , [Pb 3 I 14 ] 8– , [Pb 5 I 22 ] 8– , [Pb 5 I 16 ] 6– , [Pb 3 I 10 ] 4– , [Pb 10 I 28 ] 8– , [Pb 7 I 18 ] 4– , [Pb 18 I 44 ] 8– , and [Pb 18 I 54 (I 2 ) 9 ] 18– . Complex cations that are formed by coordination of organic amines and transition‐metal (TM) ions are good candidates for the SDAs in preparation of iodoplumbates .…”

Preparation and characterization of a novel hybrid magnetic semiconductor containing rare, one-dimensional mixed-iodide/chloride anion of lead(II)

“…Positional and displacement parameters were held equal due to the fact that the atoms are too close in space to refine independently. The final refined occupancy ratios are I(1)/Cl(1) 0.687(3)/0.313 (3). A fractional occupancy/ vacancy model was not considered as this would violate charge neutrality.…”

“…The temperature dependence of the magnetic susceptibilities was investigated over the temperature range of 2-300 K under a magnetic field of 5 kOe. 3 Pb 2 I 4.84 Cl 1.16 Á DMF] n (1) PbI 2 (92 mg, 0.2 mmol) and NaI Á 2H 2 O (9 mg, 0.05 mmol) were dissolved in DMF (10 mL) at room temperature and in air, and then NiCl 2 Á 6H 2 O (24 mg, 0.1 mmol) was added to the solution and stirred for 5 min. Finally bipy (47 mg, 0.3 mmol) was added to the solution and stirred for another 5 min, and a brown-yellow solution was obtained.…”

“…The five lead centres are essentially coplanar. 115 Mesoporous silica SBA-15 contains nanoscale channels which can be impregnated with solutions of silver nitrate. Heating the impregnated silica leads to decomposition and the formation of silver wires of controlled size, although these were not isolated from the matrix.…”
