The asymmetric unit of the title compound, [RuCl2(C6H6)(C18H27P)]·1.5C6H6, contains one mol­ecule of the RuII complex and one and a half solvent molecules as one of these is located about a centre of inversion. The RuII atom has a classical three-legged piano-stool environment being coordinated by an η6-benzene ligand [Ru—centroid = 1.6964 (6) Å], two chloride ligands with an average Ru—Cl bond length of 2.4138 (3) Å and a dicyclo­hexyl­phenyl­phosphane ligand [Ru—P = 2.3786 (3) Å]. The effective cone angle for the phosphane was calculated to be 158°. In the crystal, weak C—H...Cl hydrogen bonds link the RuII complexes into centrosymmetric dimers. The crystal packing exhibits intra- and inter­molecular C—H...π inter­actions resulting in a zigzag pattern in the [101] direction.

In the title compound, [PtCl2(C21H21O3P)2]·2C3H6O, the asymmetric unit contains a PtII ion situated on an inversion center, one chloride anion, one tris­(4-meth­oxy­lphen­yl)phosphane (L) ligand and one acetone solvent mol­ecule. The PtII ion is coordinated by two P atoms [Pt—P = 2.3196 (5) Å] from two L ligands and two chloride anions [Pt—Cl = 2.3075 (5) Å] in a distorted square-planar geometry with P—Pt—Cl angles of 88.016 (16) and 91.984 (16)°. The effective cone angle of the phosphane ligand was calculated to be 156°. Weak C—H...O and C—H...Cl hydrogen bonds hold mol­ecules together.

The title compound, [PdCl2(C21H12F9P)2]·CH2Cl2, crystallizes with two independent complex molecules (each having the PdII atom situated on an inversion centre) and a dichloro­methane molecule in the asymmetric unit. The independent PdII atoms are in perfectly linear orientations of the ligands in mutually trans positions, but distortions of the Cl—Pd—P angles ranging from 86.151 (19) to 93.849 (19)° are evident. The effective cone angles for the tris­[4-(trifluoro­meth­yl)phen­yl]phosphane ligand were calculated to be 159 and 161°. In the crystal, weak C—H...Cl/F inter­actions create a three-dimensional supramolecular network. Loose packing at two of the –CF3 groups resulted in large thermal vibrations which were treated as two-component disorders [occupancy ratios 0.50:0.50 and 0.628 (15):0.372 (15)].

In the mononuclear title compound, trans-[PtCl2(C19H17P)2], the slightly distorted square-planar coordination sphere of the PtII atom is occupied by two benzyl­diphenyl­phosphane ligands and two chloride atoms in a mutually trans geometry. The effective cone angles for the two phosphane ligands are 160 and 169°. C—H...Cl inter­actions generate infinite long chains along [01-1]. Additional C—H...π and π–π stacking interactions [centroid–centroid distance = 4.2499 (15) Å and ring slippage = 2.386 Å] are observed.

In the dimeric title compound, [Pd2Cl4{P(C8H9)3}2]·CH2Cl2, the metal complex molecule is situated about an inversion centre and is accompanied by a dichloro­methane solvent mol­ecule situated on a twofold rotation axis. The PdII atom has a slightly distorted square-planar coordination sphere. The effective cone angle for the tris­(3,5-dimethyl­phen­yl)phos­phane ligand was calculated to be 169°. In the crystal, the metal complex and solvent mol­ecules are linked via C—H...Cl inter­actions, generating chains along [10-2]. There are also C—H...π and weak π–π inter­actions present [centroid–centroid distance = 3.990 (2) Å, plane–plane distance = 3.6352 (15) Å and ring slippage = 1.644 Å], forming of a three-dimensional structure.

The title compound, [Pd2{P(C10H7)2(C10H6)}2Cl2]·2CH2Cl2, shows cyclo­metalation of one naphthalen-1-yl substituent of each of the phosphane ligands to the Pd dimer in a trans orientation; the complete dimer is generated by a centre of inversion. Two dichloro­methane solvent mol­ecules create C—H...Cl inter­actions with the metal complex, generating supermolecular layers in the ab plane. Additional C—H...π and π–π [centroid–centroid distances = 3.713 (3), 3.850 (4) and 3.926 (3) Å] inter­actions join these planes into a three-dimensional supermolecular network.

The title compound, [(μ2-CO3){Pd(P(t-C4H9)2(C12H8)}2]·CH2Cl2, the first CO3-bridged palladium dimer complex reported to date, was obtained while preparing the Pd0 complex with (2-biphen­yl)P(tBu)2. In the crystal, each palladium dimer is accompanied by a dichloro­methane solvent mol­ecule. Coordination of the carbonate and chelated phosphane ligands gives distorted square-planar environments at the Pd atoms. Important geometrical parameters include Pd—P(av.) = 2.2135 (4) Å, Pd—C(av.) = 1.9648 (16) Å and P—Pd—C = 84.05 (5) and 87.98 (5)°, and O—Pd—O′ = 60.56 (4) and 61.13 (4)°. Bonding with the carbonate O atoms shows values of 2.1616 (11) and 2.1452 (11) Å for the Pd—O—Pd bridge, whereas other Pd—O distances are slightly longer at 2.2136 (11) and 2.1946 (11) Å. One of the tert-butyl groups is disordered over two set of sites with an occupancy ratio of 0.723 (6):0.277 (6). Weak C—H...O interactions are observed propagating the molecules along the [100] direction.
