The title co-crystal, 0.95C(20)H(20)O(3)·0.05C(20)H(19)ClO(3), arises as the chloride carried over during the synthesis shares a position with an aromatic H atom; the partial occupancies are 0.947 (2) and 0.053 (2) for H and Cl, respectively. The mol-ecular structure is stabilized by intra-molecular C-H⋯O contacts, forming pseudo five- and six-membered rings with S(5) and S(6) graph-set motifs,...

The title compound, [Ni(C(12)H(9)O)Cl(C(18)H(15)P)(2)]·CH(2)Cl(2), was synthesized from the reaction between 1-acetyl-4-chloro-naphthalene, NiCl(2)·6H(2)O and triphenyl-phosphine (PPh(3)) in ethanol. The compound contains one crystallographically unique nickel ion in a pseudo-square-planar geometry.

The asymmetric unit of the title compound, C21H13ClFNO2S, contains two independent mol-ecules with similar conformations. In the mol-ecules, the thia-zole ring is essentially planar [maximum atomic deviations = 0.014 (4) and 0.023 (5) Å] and is oriented with respect to the fluoro-phenyl ring and chloro-phenyl rings at 9.96 (18) and 70.39 (18)° in one mol-ecule and at 7.50 (18) and 68.43 (18)° i...
