| Abstract | In the new tin(IV) and copper(II) complexes, cis-dichlorido- trans-dimethyl- cis-bis( N, N', N''-tricyclohexylphosphoric triamide- O)tin(IV), [Sn(CH $_{3})$ $_{2}Cl$ $_{2}(C$ $_{18}H$ $_{36}N$ $_{3}OP)$ $_{2}],$ (I), and trans-diaquabis( N, N', N''-tricyclohexylphosphoric triamide- O)copper(II) dinitrate- N, N', N''-tricyclohexylphosphoric triamide (1/2), [Cu(C $_{18}H$ $_{36}N$ $_{3}OP)$ $_{2}(H$ $_{2}O)$ $_{2}](NO$ $_{3})$ $_{2}·2C$ $_{18}H$ $_{36}N$ $_{3}OP,$ (II), the N, N', N''-tricyclohexylphosphoric triamide (PTA) ligands exist as hydrogen-bonded dimers via P=O H-N interactions around the metal center. The asymmetric unit in (I) consists of one complete complex molecule located on a general position. The Sn $^{IV}$ coordination geometry is octahedral with two cis hydrogen-bonded PTA ligands, two cis chloride ligands and two trans methyl groups. The asymmetric unit in (II) contains one half of a [Cu(PTA) $_{2}(H$ $_{2}O)$ $_{2}]$ $^{2+}$ dication on a special position (site symmetry for the Cu atom), one nitrate anion and one free PTA molecule, both on general positions. The complex adopts a square-planar trans-[CuO $_{2}O$ $_{2}]$ coordination geometry, with the Cu $^{II}$ ion coordinated by two PTA ligands and two water molecules. Each of the noncoordinated PTA molecules is hydrogen bonded to a neighboring coordinated PTA molecule and an adjacent water molecule; the phosphoryl O atom acts as a double-H-atom acceptor. The P atoms in the PTA ligands of both complexes and in the noncoordinated hydrogen-bonded molecules in (II) adopt a slightly distorted tetrahedral environment. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
