Organophosphate-chloride complexes [{(2,6-PrCH-O)POO}LnCl(CHOH)]·2CHOH, Ln = Nd (), Eu (), Gd (), and Tb () have been obtained and structurally characterized. Their reaction with 2,2':6',2″-terpyridine leads to the formation of 1:1 adducts ([{(2,6-PrCH-O)POO}LnCl(terpy)(HO)(CHOH)], Ln = Eu (), Gd (), Tb () with exception of Nd, where tris-diisopropylphenylphosphate complex [{(2,6-PrCH-O)POO}Nd) (terpy)(HO)(CHOH)] () was obtained due to the ligand metathesis. A bright luminescence observed for the Eu and Tb organophosphate complexes is the first example of an application of organophosphate ligands for 4f-ions luminescence sensitization.

The mononuclear title complex, [Eu(CHOP)(CHO)]·CHO, (), has been obtained as a minor product in the reaction between EuCl(HO) and lithium bis-(2,6-diiso-propyl-phen-yl) phosphate in a 1:3 molar ratio in a methanol medium. Its structure exhibits monoclinic (2/) symmetry at 120 K and is isostructural with the La, Ce and Nd analogs reported previously [Minyaev (2018 ▸). C, 590-598].

The structure has monoclinic (2/) symmetry at 120 K and the asymmetric unit consists of half a complex mol-ecule and one mol-ecule of toluene solvent. The diaryl phosphate ligand demonstrates a μ-κ:κ'-bridging coordination mode and the 2,2'-bi-pyridine ligand is chelating to the Li cation, generating a distorted tetra-hedral LiNO coordination polyhedron.

An important aspect of the BFI-2 is that it measures the traits at both the domain and facet levels and also controls acquiescence bias via the balanced number of true- and false-keyed items across the domains and facets. The current research evaluates factorial measurement invariance of a Russian version of the BFI-2 across sex and age within samples of 1,024 university students (Study 1) and 1,029 Internet users (Study 2).

Tumor cell rs5498 E469K (A/G) genotypes were compared with genotypes of patients with colorectal and breast cancer, residents of the Nizhniy Novgorod region. Specimens of peripheral blood and tumor foci from patients with colorectal and breast cancer and peripheral blood specimens from normal subjects were analyzed.
