AI Article Synopsis
- The compound trans-[Mo(C18H15P)2(CO)4] has not been previously analyzed using X-ray crystallography, while its cis isomer has been.
- The molecular structure shows crystallographic inversion symmetry, with the molybdenum atom at an inversion center (1a Wyckoff position).
- The tri-phenyl-phosphane groups are staggered, and the phenyl groups have varying Mo-P-C-C torsion angles due to steric effects influenced by their proximity to carbonyl ligands.
Article Abstract
The well known title compound, trans-[Mo(C18H15P)2(CO)4], has not been studied previously by X-ray crystallography, unlike its cis isomer. The complex possesses crystallographically imposed inversion symmetry, with the Mo atom residing on an inversion centre (1a Wyckoff position). The two tri-phenyl-phosphane groups are arranged in a staggered orientation. Each of the phenyl groups exhibits significantly different Mo-P-C-C torsion angles ranging from 2.6 (2) to 179.4 (1)°, most likely due to steric inter-actions based upon their positions relative to the carbonyl ligands.

Prenatal stress has a well-established link to negative biobehavioral outcomes in young children, particularly for girls, but the specific timing during gestation of these associations remains unknown. In the current study, we examined differential effects of timing of prenatal stress on two infant biobehavioral outcomes [i.e.

Background: Heart failure (HF) is a chronic, progressive condition where the heart cannot pump enough blood to meet the body's needs. In addition to the daily challenges that HF poses, acute exacerbations can lead to costly hospitalizations and increased mortality. High health care costs and the burden of HF have led to the emerging application of new technologies to support people living with HF to stay well while living in the community.

Background: Mental illness is one of the top causes of preventable pregnancy-related deaths in the United States. There are many barriers that interfere with the ability of perinatal individuals to access traditional mental health care. Digital health interventions, including app-based programs, have the potential to increase access to useful tools for these individuals.

Background: The literature is equivocal as to whether the predicted negative mental health impact of the COVID-19 pandemic came to fruition. Some quantitative studies report increased emotional problems and depression; others report improved mental health and well-being. Qualitative explorations reveal heterogeneity, with themes ranging from feelings of loss to growth and development.
