“…For example, only five Co(II/III)-Pr(III) complexes, i.e., [Pr 4 Co 4 (μ 3 -OR 5 ) 2 (μ 3 -OH) 2 (μ-OR 5 ) 2 (μ-piv) 8 (μ-N 3 ) 2 (NO 3 ) 2 ] (piv = pivalato), [PrCo(μ-OAr) 2 (H 2 O) 2 (NO 3 ) 4 ] (ArO = 3-methoxy-2-oxo-benzaldehyde), [Pr 2 Co 3 (cmipa) 4 (H 2 O) 10 ] (cmipa = 4-(carboxylatomethoxy)isophthalato), [Pr 2 Co 5 (μ 3 -OAr) 4 (μ 3 -OH) 4 (μ-ac) 2 (HNAr) 2 (NO 3 ) 6 (MeCN) 4 ] (ac = acetato, ArO = 6-chloropyridin-2-olato, HNAr = 6-chloropyridin-2-onato), and [PrCo(μ-ac) 2 (μ-L)(NO 3 ) 2 ] (L = 2,2′-(propane-1,2-diylbis((nitrilo)methylylidene))bis(6-(methoxy)phenolato)) have been reported . A group of Ni(II)-Pr(III) compounds consisting of 21 heterometallic clusters, which are mainly based on Schiff base, − salen, − and other phenolate ligands, has been reported. − A large family of Mn(II/III)-Ln(III) heterometallic clusters dominated by heteroleptic Schiff, Mannich base-carboxylate, and nitrate derivatives has also been reported. − Another group of Mn(II/III)-Ln(III) compounds consisting of various alkoxide-carboxylate-nitrate derivatives has been reported, i.e., [Ln 4 Mn 8 (μ 3 -O) 8 (hmp) 4 (benz) 12 (NO 3 ) 4 (benzH)(EtOH)] (Ln = La, Pr, Nd, Gd, Dy; and benz = benzoate), [Ln 2 Mn 4 (μ 4 -O) 2 (H 2 edte) 2 (piv/benz) 8‑ x (NO 3 ) x ] (H 2 edte = N , N , N ′, N ′-tetrakis(2-hydroxyethyl)ethylenediamine); (Ln = La, Ce, Pr, Nd, Eu, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Y, and x = 0, 2) . The presence of NO 3 – or RCOO – ligands in the lanthanide coordination sphere arose from the synthesis method applied, which involved the use of Mn(OOCR) 2 and Ln(NO) 3 as regents and amines to deprotonate the phenolic ligands.…”

In this study, a new method for the synthesis of heterometallic 3d–4f alkoxides by the direct reaction of metallic lanthanides (La, Pr, Nd, Gd) with MCl2 (M = Mn, Ni, Co) in 2-methoxyethanol was developed. The method was applied to the synthesis of the heterometallic oxo-alkoxide clusters [Ln4Mn2(μ6-O)(μ3-OR)8(HOR) x Cl6] (Ln = La (1), Nd (2), Gd (3); x = 0, 2, 4); [Pr4M2(μ6-O)(μ3-OR)8(HOR) x Cl6] (M = Co (4), Ni (5); x = 2, 4); and [Ln4Mn2(μ3-OH)2(μ3-OR)4(μ-OR)4(μ-Cl)2(HOR)4Cl6] (Ln = La (11) and Pr (12)). Mechanistic investigation led to the isolation of the homo- and heterometallic intermediates [Pr(μ-OR)(μ-Cl)(HOR)Cl] n (6), [Co4(μ3-OR)4(HOR)4Cl4] (7), [Ni4(μ3-OR)4(HOEt)4Cl4] (8), [Mn4(μ3-OR)4(HOR)2(HOEt)2Cl4] (9), and [Nd(HOR)4Cl][CoCl4] (10). In the presence of an external M(II) source at 1100 °C, 1–4 and 12 were selectively converted into binary metal oxide nanomaterials with trigonal or orthorhombic perovskite structures, i.e., LaMnO3, GdMnO3, NdMnO3, Pr0.9MnO3, and PrCoO3. Compound 5 decomposed into a mixture of homo- and heterometallic oxides. The method presented provides a valuable platform for the preparation of advanced heterometallic oxide materials with promising magnetic, luminescence, and/or catalytic applications.

“…“Salen-type” ligands are a class of coordination compounds produced when a bisaldehyde condenses with a diamine. The introduction of large electronegative oxygen atoms to the CN–group of salen-type ligands results in salamo-type probes with improved coordination flexibility, structural stability, high selectivity, and sensitivity. − Based on this background, Guo et al prepared a rigid structured fluorescent probe 1 with naphthol units and π-conjugation for dual-channel detection of H 2 S . The sensor worked in a wide pH range of 4–9 with a response time of <3 s. The deprotonation of the hydroxyl groups hindered the ICT in the probe in the presence of H 2 S, which resulted in vivid changes in the FL intensity, facilitating the detection of the biothiol.…”

Hydrogen sulfide (H 2 S) is closely linked to not only environmental hazards, but also it affects human health due to its toxic nature and the exposure risks associated with several occupational settings. Therefore, detection of this pollutant in water sources has garnered immense importance in the analytical research arena. Several research groups have devoted great efforts to explore the selective as well as sensitive methods to detect H 2 S concentrations in water. Recent studies describe different strategies for sensing this ubiquitous gas in real-life water samples. Though many of the designed and developed H 2 S detection approaches based on the use of organic small molecules facilitate qualitative/quantitative detection of the toxic contaminant in water, optical detection has been acknowledged as one of the best, attributed to the simple, highly sensitive, selective, and good repeatability features of the technique. Therefore, this review is an attempt to offer a general perspective of easy-to-use and fast response optical detection techniques for H 2 S, fluorimetry and colorimetry, over a wide variety of other instrumental platforms. The review affords a concise summary of the various design strategies adopted by various researchers in constructing small organic molecules as H 2 S sensors and offers insight into their mechanistic pathways. Moreover, it collates the salient aspects of optical detection techniques and highlights the future scope for prospective exploration in this field based on the limitations of the existing H 2 S probes.

An unusual self-assembled hetero-bimetallic [Ni(II)-Sm(III)] coordination polymer, [Ni(L)Sm(NO3)3(4,4′-bipy)]n, is prepared through a hexadentate chelating ligand 2,2′-[1,2-ethylenedioxybis(nitrilomethylidyne)]diphenol (H2L). The Ni(II)-Sm(III) coordination polymer is validated through elemental analyses, Fourier-transform infrared and UV-Visible spectroscopies, and X-ray single-crystal diffraction. The Ni(II) atom forms a twisted six-coordinated octahedron, and the Sm(III) atom is ten-coordinated, adopting a twisted bicapped square antiprism. An infinite three-dimensional-layer supramolecular structure is obtained through extensive π···π stacking and intermolecular hydrogen bonding interactions. The polymer has a good antibacterial effect against Staphylococcus aureus.
