Tetrapotassium heptacyanidomolybdate(III) dihydrate
The asymmetric unit of the title compound, KI
4[MoIII(CN)7]·2H2O, consists of one [Mo(CN)7]4− anion, four K+ cations, and two water molecules. The [MoIII(CN)7]4− anion has a seven-coordinated capped-trigonal-prismatic coordination geometry. The site-occupancy factors of the disordered water molecules were set at 0.90, 0.60 and 0.50. The H-atom positions could not be determined for two of the water molecules. The H atoms of the water with a site-occupancy factor of 0.90 were refined using O—H and H⋯H distance restraints

Poly[[diaquadeca-μ-cyanido-hexacyanidobis(4-cyanopyridine)di-μ-pyrimidine-tricopper(II)ditungsten(V)] dihydrate]
In the polymeric title compound, {[Cu3W2(CN)16(C4H4N2)2(C6H4N2)2(H2O)2]·2H2O}n, the coordination geometry of W is an eight-coordinated bicapped trigonal prism. Five of the CN groups of [W(CN)8] are bridged to Cu ions. The coordination geometries of the Cu atoms are each pseudo-octahedral; one Cu atom is located on a centre of inversion. The cyano-bridged W–Cu layers are linked by Cu-containing pillars, to form a three-dimensional network with cavities occupied by noncoordinated water and 4-cyanopyridine molecules

Current Epidemiology of the General Anesthesia Practice for Cesarean Delivery Using a Nationwide Claims Database in Japan: A Descriptive Study
The current status of general anesthesia practice for cesarean delivery in Japan remains unknown. Therefore, using a nationwide claims database, we aimed to investigate general anesthesia use for cesarean delivery over a period of 15 years, and to analyze the general anesthesia practice in Japan. Patients who claimed the Japanese general anesthesia claim code (L008) for cesarean delivery between 1 January 2005, and 31 March 2020, were analyzed. Primary endpoint was the prevalence of general anesthesia use. We used two definitions of general anesthesia: L008 code only (insurance definition) and combination of the L008 code with muscle relaxant use (clinical definition). The general anesthesia claim cohort (L008) included 10,972 cesarean deliveries at 1111 institutions from 2005 to 2020. Muscle relaxants were used in 27.3% of L008 claims cases. The rate of general anesthesia use for cesarean delivery ranged from 3.9% in clinical definition to 14.4% in insurance definition of all cesarean deliveries. We observed a temporal trend of gradual decrease in general anesthesia use, regardless of its definition (p for trend < 0.001). We recommend the clinical definition of general anesthesia as the combination of L008 code and muscle relaxant use in a claims-based approach
Poly[[diaquadeca-μ2-cyanido-κ20C:N-hexacyanido-κ6C-bis(μ2-5-methylpyrimidine-κ2N:N′)bis(5-methylpyrimidine-κN)tricopper(II)ditungstate(V)] dihydrate]
In the title complex, {[Cu3[W(CN)8]2(C5H6N2)4(H2O)2]·2H2O}n, the coordination polyhedron of the eight-coordinated WV atom is a bicapped trigonal prism, in which five CN groups are bridged to CuII ions, and the other three CN groups are terminally bound. Two of the CuII ions lie on a centre of inversion and each of the three independent CuII cations is pseudo-octahedrally coordinated. In the crystal structure, cyanido-bridged-Cu—W—Cu layers are linked by pillars involving the third independent CuII ion, generating a three-dimensional network with non-coordinating water molecules and 5-methylpyrimidine molecules. O—H...O and O—H...N hydrogen bonds involve the coordinating and non-coordinating water molecules, the CN groups and the 5-methylpyrimidine molecules
