Description of the newly observed states as molecular states
In this work, we study the strong decays of the newly observed
and assuming that
and as -wave and
molecular state, respectively. Since the was observed in the
invariant mass distributions, the partial decay width of
and into through
hadronic loops are evaluated with the help of the effective Lagrangians.
Moreover, the decay channel of is also included. The decay
process is described by the -channel , baryons and ,
mesons exchanges, respectively. By comparison with the LHCb
observation, the current results support the
with as pure molecule while the
with can not be well reproduced in the molecular state picture.
In addition, the spin-parity molecular assumptions for the
can't be conclusively determined. It may be a meson-baryon
molecule with a big component. Although the decay width of the
is of the order several MeV, it can be well
employed to test the molecule interpretations of and
2-Cyclohexyl-4-[(3,5-dimethylpiperidin-1-yl)methyl]-5-methylphenol
The title compound, C21H33NO, crystallizes with three independent molecules in the asymmetric unit. The cyclohexane and piperidine rings adopt chair conformations. The crystal packing is stabilized by intermolecular O—H⋯N and C—H⋯O hydrogen bonds, and by weak π–π stacking interactions [centroid–centroid distance = 3.876 (2) Å]
Aqua[2-(3-carboxy-5-carboxylatophenoxy)acetato-κO 1]bis(1,10-phenanthroline-κ2 N,N′)manganese(II) dihydrate
In the title complex, [Mn(C10H6O7)(C12H8N2)2(H2O)]·2H2O, the MnII atom is coordinated by two O atoms from one 2-(3-carboxy-5-carboxylatophenoxy)acetate (HOABDC2−) dianion and one water molecule and by four N atoms from two 1,10-phenanthroline (phen) ligands within a distorted octahedral geometry. O—H⋯O hydrogen bonding between –COOH and –COO− groups of adjacent molecules and between carboxylate groups and coordinated and uncoordinated water molecules leads to a three-dimensional structure which is further stabilized by weak π–π interactions of adjacent phen ligands with centroid–centroid separations of 4.2932 (1) Å
catena-Poly[cobalt(II)-bis(μ-2-aminoethanesulfonato)-κ3 N,O:O′;κ3 O:N,O′]
The hydrothermally prepared title compound, [Co(C2H6NO3S)2]n, is isotypic with its NiII analogue. The CoII cation is in a distorted octahedral environment, coordinated by four sulfonate O atoms and two N atoms from the taurine ligands. In comparison with the NiII analogue, the Co—N and Co—O bonds are longer than the Ni—N and Ni—O bonds, whereas all other bond lengths and angles as well as the hydrogen-bonding motifs are very similar in the two structures. The sulfonate groups doubly bridge symmetry-related CoII atoms, forming polymeric chains along the a axis. N—H⋯O hydrogen bonding interactions consolidate the crystal packing
