“…It can be noted that all abovementioned compounds are stable at least up to 200 °C. Interestingly, these values are lower than those we previously reported [ 42 ] for the most thermally stable Bi/Cu and Bi/Ag hybrids with 1-MeDMAP + cations (compounds 2 and 8 , respectively). Their decomposition temperatures are about 300 and 280 °C for compounds 2 and 8 , respectively.…”

“…Their decomposition temperatures are about 300 and 280 °C for compounds 2 and 8 , respectively. This was highlighted in earlier work [ 42 ] and is consistent with the stability of known discrete [M(bipy) 3 ]-templated copper and silver iodobismuthates [ 33 , 34 ] or similar one-dimensional polymers, which are stable up to 200 °C with an anomaly for [Cu(CH 3 CN) 4 ] 2 )[Cu 2 Bi 2 I 10 ] caused by the elimination of coordinated CH 3 CN at 80 °C [ 25 , 26 ]. The TG curves for compounds 1 , 3 – 5 and 7 are given in Supplementary Materials (Figures S8–S11) , while those for compound 6 , selected as the representative example within this series, are shown in Figure 6 .…”

“…We previously reported on three compounds ( 2 , 8 , and 9 ) [ 41 , 42 ]; all others were synthesized using a similar approach (see below) and characterized via XRD methods. The addition of EtOH to a 1:1 acetone/CH 3 CN mixture leads to the formation of Bi/Cu heterometallic coordination polymers.…”

“…A comparison of the structural types of one-dimensional copper and silver iodobismuthates is presented in Figure 5 . The most common isomer of [{Bi 2 Ag 2 I 10 } n ] 2n− is represented by six compounds [ 25 , 26 , 41 , 42 ], while the least common types are represented by only one example each [ 20 , 28 ].…”

“…Recently, we investigated the thermochromic behavior of a series of Te(IV) mononuclear halometallates [ 40 ] with varying substituted pyridinium-type cations, introducing a more advanced approach to such work, which involved multi-temperature spectra measurements. Continuing our work with heterometallic iodobismuthates templated by functionalized Py-based cations [ 41 , 42 ] and drawing on our experience with thermochromic bromotellurates [ 40 ], we decided to systematically study the potential thermochromic properties of the entire series of compounds.…”

Nine heterometallic iodobismuthates with the general formula Cat2{[Bi2M2I10}] (M = Cu(I), Ag(I), Cat = organic cation) were synthesized. According to X-ray diffraction data, their crystal structures consisted of {Bi2I10} units interconnected with Cu(I) or Ag(I) atoms through I-bridging ligands, forming one-dimensional polymers. The compounds are thermally stable up to 200 °C. Optical band gaps (Eg), estimated at room temperature via diffuse reflectance measurements, range from 1.81 to 2.03 eV. Thermally induced changes in optical behavior (thermochromism) for compounds 1–9 were recorded, and general correlations were established. The thermal dependence of Eg appears to be close to linear for all studied compounds.

Exploring new haloplumbate hybrids and understanding the structure‐activity relationships are of great significance for further promoting their applications in the photovoltaic fields. Herein, with the in situ‐formed [Hmd]+ (md = 2‐methyl‐1,3‐diazinane) templates, a new organic–inorganic hybrid iodoplumbate, namely [Hmd]PbI3 (1), is successfully constructed and then structurally characterized using multiple technical approaches. X‐ray crystallography studies show that compound 1 features the typical 1D chain‐like motifs of [Pb2I6]n2n−, generating the 3D supermolecular network by the extensive hydrogen bond interactions. Interestingly, compound 1 exhibits the semiconductive behavior, with an optical band gap of 2.72 eV. More attractively, the title compound has good photoelectric switching performances under the alternating light irradiation, whose photocurrent densities compete well with or surpass those of many metal halide counterparts. Further theoretical analyses reveal that the title compound has a more dispersive band structure (especially the value band) that facilitates the transport of charge carriers, which may be the main origin of its excellent optoelectronic performance. Presented in this paper also bring the studies of Hirshfeld surface, X‐ray photoelectron spectroscopy (XPS) as well as thermogravimetric analysis.

Employing metal complex cations as the structural modifiers, three new numbers of hybrid halobismuthates family, namely [NH4][Co(phen)3]BiI6 (phen=1,10‐phenanthroline; 1), [Zn(phen)2Br][Bi(phen)Br4] ⋅ H2O (2) and [Cu(2,2′‐bipy)2Br][Cu(2,2′‐bipy)2Bi2Br9] ⋅ H2O (2,2′‐bipy=2,2′‐bipyridine; 3) have been solvothermally constructed and structurally characterized. X‐ray crystallography analyses show that all compounds characteristic of abundant weak interactions feature the discrete anionic motifs. The obtained hybrid materials possess the semiconducting nature, with the visible light responding optical band gaps of 2.13–2.71 eV. Under the alternating light irradiation, they exhibit excellent photoelectric switching properties, whose photocurrent densities (0.85, 0.24, and 0.43 μA/cm2 for compounds 1–3, respectively) compare well with some high‐performance halobismuthate competitors. Further theoretical calculations of compound 1 reveal that the photosensitive [Co(phen)3]2+ cations contribute greatly to the bottom of conduction bands (CBs) and the top of valence bands (VBs), which may be the important reason for its excellent photoelectric behavior. The analyses of Hirshfeld surface, thermal stability, and X‐ray photoelectron spectroscopy were also discussed detailedly in this paper.
