The unit cell of the title compound, [Ni(CHClN)]·2CHOH, consists of a neutral complex and two methanol mol-ecules. In the complex, the two tridentate 2-(3-(4-chloro-phen-yl)-1-1,2,4-triazol-5-yl)-6-(1-pyrazol-1-yl)pyridine ligands coordinate to the central Ni ion through the N atoms of the pyrazole, pyridine and triazole groups, forming a pseudo-octa-hedral coordination sphere. Neighbouring tapered mol-ecules are linked through weak C-H(pz)⋯π(ph) inter-actions into monoperiodic chains, which are further linked through weak C-H⋯N/C inter-actions into diperiodic layers.

The X-ray diffraction study of the compound revealed that the lutetium ion is surrounded by four bis-chelating CAPh ligands, forming the complex anion [Lu ] with a coordination number of 8[O] for Lu, while PPh serves as a counter-ion. The coordination geometry around the Lu ion was determined to be a nearly perfect triangular dodeca-hedron.

The tetra-kis complex of neodymium(III), tetra-kis-{μ--[bis-(pyrrolidin-1-yl)phos-phor-yl]acet-am-id-ato}bis(pro-pan-2-ol)neodymiumsodium pro-pan-2-ol monosol-vate, [NaNd(CHClNO)(CHO)]·CHO or NaNdPyr(-PrOH)·-PrOH, with the amide type CAPh ligand bis(,-tetra-methylene)(tri-chloro-acetyl)phos-phoric acid tri-amide (HPyr), has been synthesized, crystallized and characterized by X-ray diffraction. The complex does not have the tetra-kis-(CAPh)lanthanide anion, which is typical for ester-type CAPh-based coordin-ation compounds. Instead, the NdO polyhedron is formed by one oxygen atom of a 2-propanol mol-ecule and seven oxygen atoms of CAPh ligands in the title compound.

Appropriate selection of ligands plays a huge role in optimizing their photophysical properties. Another very helpful instrument for such optimization is theoretical modelling, which permits the prediction of the emissive properties of materials through intramolecular energy transfer analysis.

The caesium salt of dimethyl--benzoyl-amido-phosphate, namely, aqua-[di-meth-yl (-benzoyl-amido-κ)phospho-nato-κ]caesium, [Cs(CHNOP)(HO)] or Cs·HO, is reported. The compound crystallizes in the monoclinic crystal system in the 2/ space group and forms a mono-periodic polymeric structure due to the bridging function of the dimethyl--benzoyl-amido-phosphate anions towards the caesium cations.
