In the title compound, [Mn(C(10)H(9)O(2))(2)(C(13)H(14)N(2))(2)], the Mn(II) ion lies on a crystallographic inversion center and has a slightly distorted octa-hedral coordination environment. Weak π-π stacking inter-actions, with centroid-centroid distances of 3.862 (2) and 3.887 (5) Å, and significant C-H⋯π inter-actions help to stabilize the crystal structure. The atoms of the unique terminal...

In the title compound, C17H18O3, the two non-spiro C atoms of the cyclo-propane ring bear a formyl and a phenyl substituent which are trans-oriented. In the crystal, mol-ecules are linked by weak C-H⋯O and C-H⋯π contacts resulting in a three-dimensional supra-molecular structure.

In the title steroid derivative, C(25)H(40)O(3), the fused cyclo-propane unit that corresponds to a part of the A ring has a β-configuration and the associated cyclo-pentane ring an envelope-shaped conformation.

in this paper, nickel oxide (nio) nanoparticles have been prepared by solid state thermal decomposition of an acyclic nickel(ii) complex (1,2-bis(2-formyl-3-methoxyphenyl)propane)nickel(ii) chloride, [nil]cl2, in an electrical furnace at optimal temperature, 450 ºc for 3.5 h. the nickel(ii) complex is obtained via solid state synthesis using nickel(ii) chloride and tetradentate o4 acyclic ligan...

In the title compound, C(11)H(7)Cl(3)N(3)O, the dihedral angle between the benzene and cyclo-propane rings is 85.8 (2)°. In the crystal, mol-ecules are linked by C-H⋯O inter-actions, generating C(5) chains propagating in the a-axis direction.

According to the results of the international testing program AREP, the most likely replacements for HCFC-22 refrigerant will be blends of HFCs. However, as concerns about their global warming potential increase, other options should also be considered. As a naturally occurring substance, propane would be an ideal refrigerant, except for its flammability. When dealing with a flammable refrigera...

In the title compound, C(26)H(22)F(2)O(2), the cyclo-propane ring makes dihedral angles of 47.6 (2), 51.3 (2) and 63.9 (2)° with the 2-fluoro-substituted phenyl ring, the unsubstituted phenyl ring and the 4-fluoro-substituted phenyl ring, respectively. There is a short C-H⋯F contact in the molecule. In the crystal, weak C-H⋯F hydrogen bonds lead to chains of mol-ecules extending along the b-axi...

In the title moleclue, C6H7N3, the mean plane of the dimethyl-amino group [maximum deviation = 0.006 (2) Å] forms a dihedral angle of 7.95 (18)° with the mean plane of the propane-dinitrile fragment [maximum deviation = 0.008 (2) Å]. In the crystal, weak C-H⋯N hydrogen bonds link the mol-ecules into a three-dimensional network.
